Vettel wins after overtaking Bottas at start as several cars collide
Hamilton up to 4th from pitlane start
Ocon, Vandoorne, Magnussen, Hartley out
Peter Wanyonyi: Bit of an overtaking masterclass on today from @LewisHamilton, external. Loving it, with nothing to lose for him, this should be fun watching!
Amanda Gregory: Relying on #bbcf1, external here in Montserrat, West Indies. Thanks chaps for doing a great job
Ellen Thompson: We are attempting to listen but phone reception is patchy in the darkest depths of Norfolk (although Twitter is working!)
It's taken Lewis Hamilton just eight laps to get into the points!
He's already up into 10th with Marcus Ericsson and Pierre Gasly just spectators in Hamilton's charge.
Felipe Massa is having a belting race. The Brazilian sweeps around the outside of Fernando Alonso at the first corner and he is up to fifth.
What a story it would be if he gets on the podium!

Very disappointed in Valtteri Bottas so far. He's had two opportunities to take the lead of this race and he hasn't been able to convert either of them.
Image source, ReutersLewis Hamilton continues his climb up the order, passing Lance Stroll with ease and he is up to 12th. Marcus Ericsson just ahead of him.
Meanwhile, Sebastian Vettel leads Valtteri Bottas by 1.1 seconds out in front.
Image source, F1.comLewis Hamilton immediately picks off Pascal Wehrlein and Brendon Hartley and he's up into 13th. Flying.
Scott Wiseman: Hoping the normal Bottas race form doesn't return, head backwards in the first half and then catch up later. He needs to pounce at the restart!
Kuku: Bottas, oh Bottas. You had one simple job and that was to step up and retain pole position.
Safety car is in and we're back racing again!
Ellen Thompson: Power cut. Really dependent on #bbcf1, external live text now to keep up to date with the #BrazilGP, external
That's why we're here. Ellen...
Replays of the start show Kevin Magnussen, Stoffel Vandoorne and Daniel Ricciardo all coming together as things got tight at the first corner.
The latter two were the big losers from it with their races over but Daniel Ricciardo is still going. He's dead last, though.
Meanwhile, good news for Felipe Massa. He is up to sixth after the first-lap drama.
The safety car is still circulating as debris from the Esteban Ocon and Romain Grosjean clash is cleared.
That incident has been noted by race stewards.

Up until this point, Bottas has done everything expected of him. He made a good getaway and I'm surprised Vettel made a better getaway but the grand prix is not over.
Image source, ReutersAdeel Ejaz: I'm sorry but I have got to question Bottas position in Mercedes again. Absolutely no back bone whatsoever. This was his chance to show he has what it takes!
Stoffel Vandoorne has one heck of a long walk back to the paddock but it's worse for Esteban Ocon, who is stranded inside the circuit.
Kayleigh: Fab, fab start Seb! Boooo Vandoorne.

Lewis Hamilton is already up to 14th. Podium finish on?

Two of the three Frenchman might be out on the spot. This is great news for Lewis Hamilton - it will bunch everyone up.
One of the McLarens is out... it's Stoffel Vandoorne. It looks like Kevin Magnussen's race is over with his Haas having come to a stop.
I wonder if they were involved in the incident that led to Daniel Ricciardo spinning?

Inch-perfect start from Vettel. He wasn't even on the grippy side of the grid.
