Max Verstappen temporarily took the spotlight off team boss Christian Horner by putting his Red Bull on pole position for the opening round of the new Formula One season in Bahrain.

The build-up to the first race of the campaign has totally been overshadowed by allegations whirling around Horner.

The 50-year-old was exonerated by Red Bull Racing parent’s company, Red Bull GmbH, following an internal probe into “inappropriate behaviour” against a female colleague on Wednesday – before hundreds of WhatsApp messages appearing to be written by him were leaked to the F1 world a day later.

However, Horner, who has always denied any wrongdoing and remains in his role, was on the world champions’ pit wall here in Bahrain to see Verstappen claim his first pole of a season in which he is expected to romp to his fourth consecutive world championship in his all-conquering Red Bull machine.

But the triple world champion was made to work for the 33rd pole of his career under the thousands of bulbs that light up the Sakhir Circuit with Ferrari’s Charles Leclerc second, two tenths back.

George Russell finished third for Mercedes, one place ahead of Ferrari’s Carlos Sainz. Lewis Hamilton will line up in ninth on the grid.

Embattled Red Bull team principal Christian Horner is back in the Formula One paddock for qualifying ahead of Saturday’s Bahrain Grand Prix.

Horner’s future is again in the spotlight after hundreds of WhatsApp messages appearing to be written by him to a female colleague were leaked.

On Wednesday, Horner was cleared to continue as Red Bull team principal following an internal probe into “inappropriate behaviour” by the F1 team’s parent company Red Bull GmbH. He has always denied the claims.

But just 24 hours later, messages and a number of images apparently exchanged between Horner and the complainant were sent from an anonymous email account to 149 members of the F1 paddock – including FIA president Mohammed ben Sulayem, F1 CEO Stefano Domenicali and the grid’s nine other team principals, as well as members of the media – on the eve of this weekend’s season-opening Bahrain Grand Prix.

Horner said in a statement: “I will not comment on anonymous speculation, but to reiterate I have always denied the allegations.

“I respected the integrity of the independent investigation and fully cooperated with it every step of the way.

“It was a thorough and fair investigation conducted by an independent specialist barrister and it has concluded dismissing the complaint made.

“I remain fully focused on the start of the season.”

On Friday, Horner, 50, was seen speaking to a Formula One official at the front of Red Bull Racing’s hospitality suite.

F1 and its governing body, the FIA, are considering whether to get involved in the controversy that’s engulfed the sport.

It is understood that neither F1’s American owners Liberty Media, nor its regulator the FIA, has seen Red Bull GmbH’s report into Horner which is thought to stretch to 150 pages – and was said to be “confidential”.

Third practice begins at 3:30pm local time (12:30pm GMT), with qualifying for Saturday’s 57-lap race due to get under way at 7pm (4pm GMT).

It is unclear at this stage whether the alleged exchanges, which have been seen by the PA news agency, formed part of the investigation – of which Horner was cleared of “inappropriate behaviour” towards a female colleague – or whether it is new evidence.

Horner has always denied the claims.

The PA news agency has approached Red Bull Racing for comment, and is also trying to confirm if the exchanges are genuine.

Horner, 50, was on the Red Bull pit wall on Thursday for both practice sessions.

Speaking on Sky Sports earlier on Thursday, he said: “I am pleased that the process is over, and I cannot comment about it.

“I am here to focus on the grand prix and the season ahead and trying to defend both of our titles.”

Horner added: “I can’t give you any further comment, but the process has been conducted and concluded.

“I am pleased to be here in Bahrain, and with the team, focused on the season ahead. Within the team it (the unity) has never been stronger.”

Mercedes boss Toto Wolff has challenged Formula One and its governing body to demand greater transparency from Red Bull’s investigation into Christian Horner.

“I am pleased that the process is over and I cannot comment about it,” he told Sky Sports. “I am focused on the season ahead. Within the team it (the unity) has never been stronger.”

Red Bull Racing’s parent company, Red Bull GmbH, said it was confident the investigation into Horner had been “fair, rigorous and impartial” but added that the report – understood to stretch to 150 pages – is “confidential”.

It is understood that neither Formula One’s owners, Liberty Media, nor its regulator, the FIA, has seen the report.

However, there were growing calls in Bahrain on Thursday night for Red Bull GmbH to share the details of their investigation.

“I just read the statement, which was pretty basic,” said Wolff. “My personal opinion is we can’t really look behind the curtain.

“There is a lady in an organisation that has spoken to HR and said there was an issue and it was investigated and yesterday the sport has received the message that it’s all fine, we’ve looked at it.

“I believe with the aspiration as a global sport, on such critical topics, it needs more transparency and I wonder what the sport’s position is?

“We’re competitors, we’re a team and we can have our own personal opinions or not. But it’s more like a general reaction or action that we as a sport need to assess, what is right in that situation and what is wrong.

“Are we talking with the right moral approach, with the values based on the speculation that is out there?

“As a sport, we cannot afford to leave things in the vague and in the opaque on critical topics like this, because this is going to catch us out.”

McLaren CEO Zak Brown agreed with his Mercedes counterpart.

“It’s the responsibility ultimately of the organisers of Formula One, the owners of Formula One, to make sure that all the racing teams and the personnel and the drivers and everyone else involved in the sport are operating in a manner in which we all live by,” said the American.

“I don’t think it’s the teams’ roles and responsibilities. That’s up to FIA and Formula One to ultimately decide and ask what they feel gives them the level of transparency they need to ultimately come to their conclusion and we just have to count on them that they fulfil that obligation to all of us.”

The PA news agency has contacted Formula One and the FIA for comment.

Horner, who has protested his innocence throughout, was questioned by a lawyer for eight hours earlier this month at a secret London location.

He has been Red Bull team principal since they entered F1 19 years ago and is the longest-serving boss on the grid.

He has overseen seven drivers’ world championships and six constructors’ titles.

Red Bull have dominated the sport in recent seasons and last year won 21 of the 22 races, with Dutch driver Max Verstappen setting a new record for 10 consecutive victories as he wrapped up his third title.

Horner, who is married to former Spice Girls singer Geri Halliwell, was awarded a CBE for his services to motorsport in the New Year Honours.

Christian Horner will continue as team principal of the Red Bull Formula One team after he was cleared of “inappropriate behaviour”.

Red Bull Racing’s parent company Red Bull GmbH announced on February 5 that Horner was under investigation following an accusation made against him by a female colleague.

Horner emphatically denied the claim, and the 50-year-old – who arrived in Bahrain on Wednesday ahead of this weekend’s opening race of the season – has been cleared of wrongdoing.

Red Bull GmbH said it was confident the investigation had been “fair, rigorous and impartial”, but added that the report – understood to stretch to 150 pages – is “confidential”.

Mercedes boss Toto Wolff had called for the investigation to be conducted with transparency – but no details of the allegations against Horner were reported.

Horner has made no public comment. He is expected to be on Red Bull’s pit-wall in Bahrain for practice on Thursday. The complainant also has a right to appeal the verdict.

A statement from Red Bull GmbH read: “The independent investigation into the allegations made against Mr Horner is complete, and Red Bull can confirm that the grievance has been dismissed.

“The complainant has a right of appeal. Red Bull is confident that the investigation has been fair, rigorous and impartial.

“The investigation report is confidential and contains the private information of the parties and third parties who assisted in the investigation, and therefore we will not be commenting further out of respect for all concerned. Red Bull will continue striving to meet the highest workplace standards.”

Horner, who has protested his innocence throughout, was questioned by a lawyer for eight hours earlier this month at a secret London location.

During the internal probe, he continued to be present for official Red Bull activities – including a car launch in Milton Keynes earlier this month – where he insisted it was “business as usual” – and also pre-season testing in Bahrain last week.

Horner flew back to England as he awaited his fate before heading back to the Gulf kingdom on a private jet on Wednesday.

Addressing the controversy surrounding Horner, seven-time world champion Lewis Hamilton said earlier on Wednesday: “We always have to do more to try to make the sport and the environment for people to work in feel safe and inclusive.

“Any allegations have to be taken very seriously. We don’t know everything that has gone on but it needs to be resolved because it is hanging over the sport.

“It will be interesting to see how it is dealt with, and the effect that it may or may not have on the sport moving forward. It is a really important moment for the sport to make sure that we stand true to our values.”

Horner, who is married to former Spice Girls singer Geri Halliwell, was awarded a CBE for his services to motorsport in the New Year Honours list.

Verstappen said before Horner had been cleared of any wrongdoing: “He is very important otherwise he wouldn’t have been in that position for such a long time.

“Everyone is focused on what happens on track and we are in a good mood to get going again.”

Christian Horner will remain in his post as Red Bull team principal.

Red Bull Racing’s parent company Red Bull GmbH announced on February 5 that Horner was under investigation following an accusation of “inappropriate behaviour” by a female colleague.

Horner emphatically denied the claim and the 50-year-old, who arrived in Bahrain on Wednesday ahead of this weekend’s opening race of the Formula One season, will stay on as team principal of the British team.

“The investigation report is confidential and contains the private information of the parties and third parties who assisted in the investigation, and therefore we will not be commenting further out of respect for all concerned. Red Bull will continue striving to meet the highest workplace standards.”

Horner fully co-operated with the investigation, having been questioned by a lawyer for around eight hours earlier this month at a secret London location away from the team’s Milton Keynes headquarters.

During the internal probe, he continued to be present for official Red Bull activities – including the new car launch in Milton Keynes earlier this month, and also pre-season testing in Bahrain last week.

Asked whether he had considered temporarily stepping aside until the conclusion, Horner stressed it was “business as usual”.

He said: “Obviously, I fully deny any accusations that have been made against me, but of course I’ll work with that process, which I hope is concluded in the near future.”

Horner has been Red Bull team principal since they entered F1 19 years ago and is the longest-serving boss on the grid.

Under Horner’s leadership, he has overseen seven drivers’ world championships and six constructors’ titles at the British-based F1 team.

“If Lewis were to leave,” pondered George Russell as he addressed the prospect of Hamilton joining Ferrari. “That would put Mercedes in a tricky spot. It would almost look like he’s lost faith in the team.”

Russell was speaking in an episode of Netflix’s newly-released Drive to Survive series – a chapter the Mercedes’ PR machine envisaged would celebrate Hamilton’s decision to stay with them.

Hamilton, after all, had signed a two-year contract extension last August to remain with the Silver Arrows until the end of 2025.

But following Hamilton’s shock decision to tear up his contract a year early in favour of a move to Ferrari, Russell’s remarks – too late to be pulled from Netflix’s sixth season – shed a very public spotlight on the awkward dynamic that faces the grid’s once-dominant team and its superstar driver ahead of the new season which starts in Bahrain on Saturday night.

Mercedes transformed Hamilton from a man with a single world championship to a one-man winning machine. He has seven world championships and 103 victories. No other driver in history can boast such an impressive resume.

But Hamilton is motivated by capturing the eighth title he believes he was robbed of in Abu Dhabi in 2021. And the 39-year-old no longer thinks he can achieve the record-breaking feat with Mercedes. As Russell would say, he’s lost the faith.

Can Hamilton be blamed? He has not tasted victory for two years. Mercedes did not win one of the 22 rounds last season. He heads into the new campaign as a 16/1 underdog to win the championship.

This year is being called Hamilton’s last dance with Mercedes. But do not expect it to be a samba.

Mercedes will remain at the sharp end of the grid this season. They have ditched the concept that has failed them so miserably for the past two years and introduced a new design philosophy – one that both Hamilton and Russell said is more predictable and easier to drive.

But will it possess the speed to knock Red Bull and Max Verstappen off their perch?

F1 works in cycles and, although Mercedes carried Hamilton to six championships in seven glorious years, this period in time belongs to the team from Milton Keynes, despite the on-going controversy surrounding its team principal Christian Horner and allegations of inappropriate behaviour made against him by a female colleague.

Horner continues to deny the claims and a resolution is expected before Saturday’s curtain raiser.

Red Bull swept all before them in 2023, winning every race bar one, with Verstappen taking 19 victories as he waltzed to a hat-trick of titles.

Such was their superiority, Red Bull and their genius designer Adrian Newey could afford to start work on this year’s challenger long before the others.

And the finished product, unveiled in all its glory at last week’s test, sent shivers down the spines of their competitors. The fear, for those not in a Red Bull cockpit, is that Newey’s latest masterpiece is an improvement on its brilliant predecessor.

Given the sport’s rule book is largely unchanged and the budget cap means rival teams can no longer break the bank to discover a winning solution, Verstappen heads into this mammoth 24-round campaign as the favourite to become only the sixth driver in history with four world titles to his name.

Alarmingly for the neutrals, Damon Hill, the 1996 world champion, has predicted this season will be “one long victory lap” for Verstappen and his all-conquering team – and that’s before a wheel has been turned in anger.

But all is not lost – and that is when we return to Hamilton.

While Verstappen could prove an unstoppable force on track, Hamilton’s agonisingly long goodbye with Mercedes – one that is set to stretch nine months and six days – will provide a fascinating subplot.

The new Formula One season begins in Bahrain on Saturday with Max Verstappen bidding to win a fourth consecutive world championship.

Here, the PA news agency looks at the key questions heading into the 2024 campaign.

Who is the favourite to win the title?

Red Bull’s preparations for the new season have been overshadowed by allegations facing team principal Christian Horner. Horner, who is fighting to save his career following a claim of “inappropriate behaviour” by a female colleague, insists it is business as usual at Red Bull. Off-track it has been anything but for the team which has dominated the sport for the past two seasons. But on-track it has been precisely that.

Verstappen — in an upgrade of the machine which carried him to 19 victories from 22 rounds last year — set a blistering pace on the opening day of last week’s test, finishing 1.1 seconds quicker than anybody else.

Damon Hill, the 1996 world champion, summed up the ominous feeling in the paddock. Writing about Verstappen on ‘X’ he said: “He’s gloating. He’s taunting us. He knows. This year is going to be one long victory lap. You cannot begrudge anyone their success. All we can do is watch and admire.”

So, can anyone challenge Verstappen and Red Bull?

Ferrari ended last year with five pole positions from the final nine races and Carlos Sainz secured the only non-Red Bull win of the season in Singapore. The Italian team have worked hard over the winter on translating their one-lap pace into race conditions, where they tended to struggle in 2023.

They will take solace from a trouble-free test and their pace appeared relatively encouraging, too. Sainz topped the time charts on the second day, while Leclerc ended the final day quickest – albeit on speedier rubber than Verstappen.

An upbeat Leclerc said: “We are in a much better place and it is an easier car to drive. The feeling was good. We have been consistent straight away and this will help us in the race.”

And what about Lewis Hamilton and Mercedes?

Hamilton stunned the sporting world by choosing to quit Mercedes and join Ferrari in 2025. The news broke earlier this month and is likely to be difficult for those at Mercedes to digest. Hamilton took the decision – one he described as the hardest of his life – after two winless years with the Silver Arrows.

Mercedes are armed with a new design philosophy for the new campaign but – although both Hamilton and team-mate George Russell spoke of an improved, more reliable machine – there was little to suggest from testing that they have closed the gap to Red Bull.

Mercedes finished ahead of Ferrari in last year’s constructors’ championship but do not be surprised if the Scuderia start the new season ahead of them.

What about the other teams?

McLaren came alive in the second half of 2023, with Lando Norris scoring seven podiums. But the British team looked short of last year’s form in Bahrain last week – although it is a track which has not always suited them in recent seasons.

Aston Martin finished fifth in the constructors’ championship, with Fernando Alonso, now 42, leading their charge for a second season. Alpine are set to head the midfield, with Williams, the newly-rebranded RB and Sauber teams (nee AlphaTauri and Alfa Romeo) and Haas likely to follow.

Have there been any driver changes?

No. This season’s line-up is the same as the previous year – the first time that’s ever happened. But with Hamilton already announcing his move to Ferrari for 2025 and 13 of the 20 drivers out of contract at the end of the season – next year’s grid is sure to have a whole different feel about it.

What else happened during the winter break?

Aside from Hamilton’s blockbuster transfer, his soon-to-be Ferrari team-mate Charles Leclerc penned a new deal which is expected to keep the 26-year-old Monegasque dressed in red until 2029. Lando Norris also extended his stay with McLaren until at least the end of 2026.

Andretti’s move to become the 11th team on the grid was blocked by F1 bosses. The British Grand Prix will remain on the calendar for another decade after Silverstone agreed a new long-term deal with F1’s American owners’ Liberty Media.

How does the calendar look?

There will be a record-breaking 24 races – the longest season in history – starting in Bahrain on March 2 and ending in Abu Dhabi nine months and six days later.

The Chinese Grand Prix returns after five years away, while the round in Japan moves from its traditional October slot to April. The roster features six sprint races in China, Miami, Austria, Austin, Qatar and Brazil. The format has been tinkered with, too. Qualifying for the sprint will now take place on Friday, with the grid for Sunday’s main event decided on Saturday, following the shortened race.

What else do I need to know?

The opening two races will both take place on a Saturday. The Muslim holy period of Ramadan starts on March 10. As such, the second round in Saudi Arabia has been brought forward by a day. FIA rules stipulate there must one week between races, meaning the Bahrain GP will also be 24 hours earlier than usual.

Christian Horner wants his Red Bull future to be resolved “as soon as possible” as the embattled team principal fights to save his Formula One career.

Red Bull Racing’s parent company Red Bull GmbH announced on February 5 that Horner is being investigated following an accusation of “inappropriate behaviour” by a female colleague. Horner denies the claim.

Horner addressed the media alongside four other F1 team principals on the second day of this week’s three-day test in Bahrain on Thursday. The new season starts in the Gulf kingdom next Saturday.

Asked why he has not moved aside as team principal and chief executive of Red Bull Racing with the investigation under way, Horner replied: “As you are well aware there is a process going on which I form part of, and as I form part of that process, I am afraid I cannot comment on it.”

Horner was then asked if he could provided a timeline as to when the investigation might be over.

The 50-year-old added: “I am dreadfully sorry but I really can’t comment on the process or the timescale.

“Everybody would like a conclusion as soon as possible. But I am really not at liberty to comment about the process.”

Sources have indicated to the PA news agency that there could be a resolution before the opening race on March 2.

On Wednesday, Mercedes boss Toto Wolff called for Red Bull’s probe to be transparent, and said the controversy is “an issue for all of Formula One”.

McLaren chief executive Zak Brown, speaking in the same press conference as Horner on Thursday, echoed Wolff’s comments.

“The allegations are extremely serious,” said Brown. “McLaren hold themselves to the highest standards of diversity, equality and inclusion.

“These are extremely important to us and our partners, and to everyone in Formula One.

“Red Bull Corporation has launched an investigation, and all we hope and assume is that it will be handled in a very transparent way, and as the FIA and Formula One has said, swiftly, because these are not the headlines that Formula One wants or needs at this time.”

Red Bull won all but one of the 22 races last year as Max Verstappen stormed to the world championship.

The Dutch driver, in his heavily upgraded machine, set an impressive pace on the opening day in Bahrain, finishing 1.1 seconds clear of anyone else.

Mercedes’ George Russell said: “Red Bull are definitely the favourites and definitely a step ahead of everyone here in Bahrain. They have had an impressive winter, no doubt.

“Hopefully Red Bull are already in that sweet spot, and we can close the gap, but it is going to take a lot of hard work to do so.”

Mercedes boss Toto Wolff has called for Red Bull’s investigation into Christian Horner to be transparent – and said the controversy is “an issue for all of Formula One”.

Horner is under investigation by the racing team’s parent company Red Bull GmbH following a claim of “inappropriate behaviour” by a female colleague.

The 50-year-old emphatically denies the accusation and remains in his role as Red Bull team principal.

He is in Bahrain for this week’s three-day test ahead of the opening race, also in the Gulf Kingdom, on March 2.

And Horner has stated it is his intention to be in his post for the start of the new campaign.

“It is clear,” Wolff said when asked to address the allegations during the lunch interval on the first day of testing.

“Formula One and the teams stand for inclusion, equality, fairness and diversity, and that is not only about talking about it, but living it day in, day out. These are just standards we set ourselves.

“We are a global sport and one of the most important sport platforms in the world and role models, too.

“But having said that, there is a lot of speculation that has been happening over the past weeks, and lots of things that are going on.

“What is important at that stage is for a process with rigour. I think what Red Bull has started as an independent investigation, if this is done in the right way, with transparency, that is something we need to look at.

“What the outcomes are, what it means for Formula One, and how we can learn from that because we want to talk about racing cars, and we want to talk about the sport, rather than these very, very critical topics that are more than just a team issue.

“It is phenomenon, and an issue for all of Formula One, and every individual that works out there.”

Horner is due to be in the media spotlight at an F1 press conference alongside four other team principals on Thursday.

Speaking at Red Bull’s car launch, last week, Horner said he was unable to provide a timeline as to when the investigation will be completed.

It is understood both Red Bull and Horner are keen for a swift resolution, but sources have indicated that a conclusion is not imminent. F1 bosses have called for the controversy to be “clarified at the earliest opportunity”.

Max Verstappen put Red Bull’s off-track troubles to one side by setting the pace in the opening session on Wednesday.

The three-time world champion ended the running nearly seven tenths quicker than Ferrari’s Charles Leclerc, with Aston Martin’s Fernando Alonso in third, eight tenths back, and the only other driver within one second of Verstappen.

George Russell was sixth for Mercedes, 1.68 secs off the pace. Lewis Hamilton gets his first taste of the final Mercedes he will drive on Thursday ahead of his blockbuster switch to Ferrari next year.

Red Bull team principal Christian Horner will be in Bahrain for Formula One’s first day of testing on Wednesday.

The 50-year-old is fighting to save his career in the sport following an allegation of “inappropriate behaviour” by a female colleague. Horner categorically denies the claims.

The PA news agency understands Horner, who remains under investigation by the racing team’s parent company Red Bull GmbH, is due to arrive in the Gulf kingdom on Tuesday evening.

Max Verstappen will take to the wheel of the Red Bull he hopes will carry him to a fourth straight world championship on Wednesday – the first of three days of testing – and Horner is set to be in the paddock to oversee his superstar driver in action.

Horner is also due to speak at an F1 press conference alongside four other team principals a day later.

The opening round of this season’s championship takes place in Bahrain on March 2.

Speaking at Red Bull Racing’s car launch in Milton Keynes last week, Horner insisted he would be in his position for the first race.

Horner said he was unable to provide a timeline as to when the investigation will be completed.

It is understood both Red Bull and Horner are keen for a swift resolution, but sources have indicated that a conclusion is not imminent.

F1 bosses have called for the controversy to be “clarified at the earliest opportunity”.

Last season Red Bull won all but one of the 22 races, with Verstappen taking his third world championship in as many years.

Speaking last week, a defiant Horner said: “The process has been going on in the background.

“Obviously, there’s been a day job to be getting on with, which is gearing up for the season ahead of us.

“I am confident in the process, which I have fully complied with and will continue to do so, and absolutely deny any of the allegations that have been made against me.

“For me, it is business as normal. If it wasn’t, I wouldn’t be here.”

Formula One’s governing body, the FIA, said it will not comment on Christian Horner’s future until Red Bull’s investigation has been concluded – but added it “remains committed to upholding the highest standards of integrity, fairness and inclusivity within the sport”.

Horner’s role as Red Bull team principal remains in the balance following a claim of “inappropriate behaviour” by a female colleague. Horner emphatically denies the allegations.

On Sunday, F1 bosses called for the controversy to be “clarified at the earliest opportunity”. The new season gets under way on March 2.

A statement from the FIA on Monday read: “In relation to the independent investigation currently being undertaken by Red Bull GMbH, the FIA reiterates that until such time as the investigation has concluded and the outcome is known, we will not be commenting further.

“The FIA remains committed to upholding the highest standards of integrity, fairness and inclusivity within the sport.”

Speaking at Red Bull Racing’s car launch in Milton Keynes last Thursday, Horner, 50, insisted he would be in Bahrain for the opening race.

Horner said he was unable to provide a timeline as to when the investigation by the racing team’s parent company, Red Bull GmBH, will be completed.

It is understood both Red Bull and Horner are keen for a swift resolution and sources have indicated to the PA news agency that there could yet be a conclusion by the end of the week.

However, it is thought unlikely that a verdict will be found before this week’s three-day test in Bahrain which starts on Wednesday.

An F1 spokesperson said: “We have noted that Red Bull has instigated an independent investigation into internal allegations at Red Bull Racing.

“We hope that the matter will be clarified at the earliest opportunity, after a fair and thorough process, and we will not comment further at this time.”

Last season Red Bull won all but one of the 22 races, with Max Verstappen taking his third world championship in as many years.

A defiant Christian Horner said he will not be forced out of Red Bull – and vowed to be in his post as team principal for the first Formula One race of the season.

Horner broke his silence on Thursday after an investigation was launched into an allegation of “inappropriate behaviour” against him by a female colleague.

The 50-year-old, speaking at Red Bull’s car launch in Milton Keynes, revealed he had been “overwhelmed” by messages of goodwill from within the sport, and said his wife, former Spice Girls singer Geri Halliwell, has been “very supportive”.

He also continued to emphatically deny the allegations made against him.

Asked if he will be in Bahrain for the first round of Max Verstappen’s championship defence on March 2, Horner replied: “Yes. I will be in Bahrain.

“The process has been going on in the background. Obviously, there’s been a day job to be getting on with, which is gearing up for the season ahead of us.

“I have a hugely supportive family, a very supportive wife. I have felt the support from within the business and our partners, and the support from within the industry has been overwhelming, too.

“I am confident in the process, which I have fully complied with and will continue to do so, and absolutely deny any of the allegations that have been made against me.

“For me, it is business as normal. If it wasn’t, I wouldn’t be here.”

Direct questions relating to the internal investigation launched by Red Bull Racing’s parent company Red Bull GmBH – which leaves Horner’s career in the balance – were strictly off-limits.

Horner has been in charge of the F1 team for two decades, but he insisted the investigation has not forced him to ponder resigning.

“Not at all, absolutely not,” said Horner when asked if he had considered his role as team principal and chief executive of the racing team.

“I am fully committed. I built this team. I convinced people to come and work here.

“I’ve been here since the beginning. There have been highs and lows along the way. We have won 113 races. We have won seven drivers’ world championships. We’ve won six constructors’ world championships in 19 seasons, and that’s in the history books.

“But it’s about what lies ahead, because that’s what’s important. So my focus is on the future.”

There had been a strong desire for Horner’s future to be concluded before Thursday’s presentation which marked the 20th anniversary of Red Bull’s involvement as a constructor in the sport.

Horner, who was quizzed by a lawyer for eight hours last Friday, said he did not know when the probe will be concluded.

There will be three days of testing, starting next Wednesday, in Bahrain ahead of the first race, also in the Gulf kingdom. And sources have indicated Horner could face further rounds of questioning as he bids to prove his innocence.

The investigation against Horner has undoubtedly overshadowed the world champions’ preparations for the forthcoming campaign.

Last year, Red Bull won all but one of the 22 races, with Verstappen taking his third world title in as many years.

But the Dutch driver, 26, said: “I don’t feel it (the investigation) has been a distraction.

“Everyone is very focused and very motivated. The spirit in the team has been fantastic. It’s been honestly better than ever.”

Pressed on his relationship with Horner, the triple world champion added: “It is very good.

“We’ve seen each other quite a few times. We’ve achieved a lot of things together so that doesn’t change suddenly.

“My contact with Christian has been the same as on the first day. It’s been like normal.”

Christian Horner will face the media on Thursday as an investigation into an allegation of “inappropriate behaviour” against the Red Bull team principal continues.

The embattled boss is due to attend the world champions’ car launch at their Milton Keynes headquarters in what will be his first public appearance since the accusation by a female colleague surfaced at the beginning of last week. Horner, 50, categorically denies the claim.

For now, Horner remains in his role as team principal and was present at a behind-closed-doors Red Bull test at Silverstone on Tuesday ahead of the new season which starts in just over a fortnight.

Red Bull will unveil their new car on Thursday and Horner is expected to address the media – although the PA news agency understands legalities around the process mean that questions relating to the internal investigation will be off-limits.

Last week, Horner was quizzed by a lawyer for eight hours as part of the probe by Red Bull Racing’s parent company Red Bull GmBH.

There had been a strong desire for Horner’s future to be resolved before Thursday’s launch but sources have indicated that he could face further rounds of questioning as he bids to prove his innocence.

Horner has been Red Bull team principal since they entered F1 19 years ago and is the longest-serving boss on the grid.

During that period he has overseen seven drivers’ world championships and six constructors’ titles. Red Bull have dominated the sport in recent seasons and last year won 21 of the 22 races, with Max Verstappen setting a new record for 10 consecutive victories.
