Remarkable late drama at the Azerbaijan Grand Prix saw Sergio Perez handed victory after Max Verstappen crashed out and title rival Lewis Hamilton incredibly finished outside the points.

Verstappen looked to be coasting to a second consecutive Formula One win and seventh straight podium – both career firsts.

The Red Bull driver, four points ahead of Hamilton in the standings prior to the race, was well in the clear after earlier benefitting from a slow Hamilton pit stop.

But Verstappen's left-rear tyre blew out and ended his race, prompting the furious Dutchman to kick his car in anger.

Lance Stroll had encountered the same issue with the hard Pirelli tyres, swerving out of control when he had been fourth, albeit without pitting.

A red flag – requested by a concerned Red Bull team – followed Verstappen's crash with just three laps remaining, meaning a standing start with Perez ahead of Hamilton on the front row of the grid following the delay.

In another twist, Hamilton and his smoking brakes careered off the circuit from the restart and Perez raced away to lift Red Bull spirits.

With Hamilton way back in 15th, it meant a positive end to the day for Verstappen's team, even if the season leader will continue to rue his misfortune.

Both Verstappen and Perez jumped ahead of Hamilton when he was delayed in the pit lane by Pierre Gasly, having quickly caught pole-sitter Charles Leclerc.

Stroll's mishap threw a spanner in the works, yet Verstappen pulled ahead clear from the restart following the safety car, with Perez again getting the better of Hamilton.

Sebastian Vettel's climb to fourth and attempt to reel in old foe Hamilton looked the most likely source of intrigue in the closing stages, only for Verstappen's blow to bring the race to a standstill.

Hamilton admitted his error when his restart sensationally failed, though, and Perez hung on, his car breaking down moments after crossing the line before Vettel – who achieved a first Aston Martin podium.

Max Verstappen's title challenge was blown slightly off course as a deleted lap time handed pole position at the Portuguese Grand Prix to Valtteri Bottas.

The Red Bull driver was victorious last time out at Imola and his team again looked to have the best pace in Portimao ahead of qualifying.

But Verstappen complained of a lack of straight-line speed in Q1 and struggled with grip throughout amid windy conditions on the Algarve.

And a correction to avoid a crash at Turn 4 saw a lap that would have been the fastest of Q3 chalked off for exceeding track limits, and he could not replicate it on his sole flying lap that did count.

It meant Bottas claimed pole with a time of one minute and 18.348 seconds, with Mercedes team-mate Lewis Hamilton denied a 100th career pole as he took second, missing out by just 0.007secs.

Verstappen, whose disqualified lap was a 1:18.209, conceded he has found little joy out of the challenge presented by the Algarve International Circuit.

"Whole qualifying was very difficult to drive, was struggling with grip," he said in the post-session interviews. 

"I was quite confident I could do another good lap, [but a] car in front in the last corners disturbs you.

"It's of course not ideal, we'll try to fight them [Mercedes] in the race and see what we can do. Hopefully everything stabilises, up until now it's not been a lot of fun to drive here."

Bottas' emotions were a marked contrast, the Finn left unsurprisingly satisfied with the 17th pole position of his career.

"Feels like it's been a while. It's been a weak point for me in the first two races, getting the tyres to work," said Bottas. 

"The team have been working hard all weekend and we have a good position for tomorrow.

"Starting with the medium tyre tomorrow is good, and it opens up opportunities that we can go as long as we want in the first stint.

Hamilton added: "A great job by Valtteri and our teams for us both to be on the front row, it was not expected. We have to be happy for that, it was not the perfect lap but I gave it everything.

"You can never be satisfied, we exist to keep moving forward but I'm happy with what we're doing and the steps we're taking."

The Red Bulls were far from the only ones to struggle with the wind, McLaren's Daniel Ricciardo failing to make it out of Q1, he will start 16th.

But there was better news for Sebastian Vettel, who made it through to Q3 for the first time since joining Aston Martin.

Vettel will start 10th in a race that will provide plenty of intrigue after an unanticipated shakeup at the front, with both Red Bulls behind an all-Mercedes front row but expected to have better race pace.

Sergio Perez, who will start fourth, told Sky Sports: "I never really got on top of the car in this session, I lacked a bit getting into a rhythm.

"Not really everything worked but at least we have a good starting position, our race pace seems to be better."

If that proves to be the case, it will set the stage for a fascinating duel on Sunday.
