Bottas has a big lock up on his fast lap.

Bottas heads out and Hamilton follows him.
Final word will go to the Briton.

Ocon blinks first on the final runs.
The Force India man is in P8 as it stands.
Team-mate Perez and McLaren's Vandoorne follow him out.

Image source, Getty ImagesWhat Silverstone has become this year - to those of you who are technically minded - is the cars are three seconds a lap faster than last year as the corners have been straightened out and become a more power sensitive track. That hurts Red Bull and helps the Mercedes and Ferrari cars.

Max Verstappen - Red Bull's sole driver in this session - completes his first hot lap and slots into fifth place, over a second slower than Hamilton.

A 1:27.580 for Bottas is the first time on the board, but Hamilton blasts through seconds later and goes quicker by three tenths of a second.
Perez and Ocon in the Force Indias then set their times - two seconds off the pace of the Mercedes. Ouch.

A reminder of your protagonists in this session:
Hamilton, Bottas, Vettel, Raikkonen, Hulkenberg, Verstappen, Ocon, Perez, Grosjean, Vandoorne
Bottas will take a five-place grid penalty, don't forget, so pole is likely to come down to a straight fight between Hamilton and Vettel.

BBC Radio 5 live commentatorThe standout from that session for me was Stoffel Vandoorne, who went 10th fastest. He was quicker than McLaren team-mate Fernando Alonso - the first time this year that has happened. It's a great confidence boost for Vandoorne and to put one over on Alonso will be good for his end-of-year CV.

BBC Sport at SilverstoneIt has taken a while but I've bumped into a colourful group of characters at Silverstone. These chaps are apparently dressed up as dead popstars. Got to be a stag do?
"No we just fancied it," said one of their group.
"What did you think of Alonso's Q1 lap," I asked.
"What did he do?" was the response.
It is fair to say the beers were flowing.
