Daniel Ricciardo has a five-place grid penalty for a new turbo, which means he will start in eleventh.

Vettel is in trouble with scalesgate, so we shall find out whether that's grounds for a penalty, and what the damage is tomorrow.

Mercedes' 100th pole.

Hamilton's 82nd pole, 10 of those came from this season.

Tomorrow is Fernando Alonso's penultimate race in Formula 1.

He says: "The races have been the same from July so there are no surprises. And in Abu Dhabi it will be my last race, we will put in a lot of emotions and a lot of effort and we will be out in Q1 because there are no miracles from one race to another."

Hamilton had his own incident in qualifying, when he narrowly avoided a crash with Williams driver Sergey Sitorkin at the start of second qualifying.

The drivers were all preparing for their first flying laps and Hamilton suddenly saw the Russian coming up behind him at much higher speed approaching Turn 12.

Hamilton moved left to try to get out of the way but Sirotkin was already going that way and had to take avoiding action.

But there has been no sign yet of a stewards’ investigation and Sirotkin said he had no problem with the incident.

Jack Allum: Could we have some balance on here please? Why on Earth is Hamilton being allowed to get away with clearly blocking Kimi on a hot lap, and also driving extremely dangerously and nearly crashing into the Williams? Or is only Vettel allowed to be criticised?

We may have an answer for you Jack...

World champion Lewis Hamilton beat Ferrari's Sebastian Vettel to pole position at the Brazilian Grand Prix.

Hamilton was 0.093 seconds clear of his former title rival at the end of a tight and tense battle, with their team-mates Valtteri Bottas and Kimi Raikkonen next.

Vettel, though, faces an investigation for an infraction at the weigh-bridge, where he failed to follow stewards' instructions.

The Red Bulls of Max Verstappen and Daniel Ricciardo were fifth and sixth, but the Australian has a five-place penalty.

Jeroen on Twitter: See, that's the key to getting the best out of Marcus Ericsson: you just need to sack him.

Fair point, with the usual caveat that #ME9 is like an old diesel. He takes his time to get going in each new series.

So on that calculation, Ericsson should be useful in IndyCar in circa 2027?

A parting gift for long-suffering Ericsson Behind the big three, Swede Marcus Ericsson took a career-best seventh place - which will become sixth on the grid with Ricciardo's penalty for using too many engine parts - two races before what is likely the end of his F1 career.

Ericsson has been dropped by Sauber for next season and is to race in Indycars in the US, although he will remain the team's reserve driver. He beat team-mate Charles Leclerc, who is moving to Ferrari to partner Vettel next season in a swap with Raikkonen, by 0.196secs.

Surprise surprise, even after Charles Leclerc's awesome lap in Q2, his teammate managed to out-qualify him.

Valtteri Bottas, who starts P3 tomorrow, says: "Not too far away but here the margins are always small here. I know it was hard but I couldn't take it today. I was more than two tenths up but then I lost it in Q3 on the straight."

"It depends on the situation, but once the rain started coming down, but sometimes you need to go for it and try."

Vettel facing an investigation refusing to turn off the engine when being weighed by the FIA, "which makes it difficult to get a stable result" and "drove off the scales under its own power, and by doing so, he destroyed the scales".

In addition to his other misdemeanours, he also drove at a steward who was standing in his way preventing him going on the scales until they were ready.
