0' Rosberg again! He laps in 1:18.899 and it's a Williams one-two with Nakajima second.

0' Good rescue work by Timo Glock, who runs wide onto the grass but makes a superb recovery to swerve back onto hangar straight.

1' Good lap from Jarno Trulli, a 1:19.125 which is the best of the weekend so far. Meanwhile, Jenson Button rather gets in Fernando Alonso's way going into the start-finish straight.

3' 1:19.596 for Massa, who goes to the top of the time sheets.

5' Hamilton up into fourth, and the world champion will be optimistic that he can make the final session of qualifying.

8' Massa goes second, but Vettel is still the only man to have gone underneath 1:20.

11' Dynamite lap from Sebastian Vettel, who clocks a 1:19.809. Red Bull look like they will be tough to beat this weekend. Jenson Button certainly thinks so. Button's reaction on Friday

14' Lewis Hamilton is going fairly well in eighth place, although he is losing time in the first sector. Trulli fastest, 1:20.087.

16' Plenty of action as the sun pokes its way tentatively through the clouds. Nakajima is fastest with 1:20.256, and Button is second.

18' Hamilton runs wide around Stowe and goes over the grass. The McLaren mechanics won't thank him for that.

20' A good session for Williams, this. Rosberg goes quicker again with a 1:20.655. The track has almost completely dried out, although it is a fairly dry day in Northamptonshire.

22' Nico Rosberg goes quickest in 1:21.375, while Lewis Hamilton is fifth. Nothing from Jenson Button yet.

23' Here's the second session: Free practice 2

26' A few more hot laps being recorded here,with Williams man Kazuki Nakajima quickest in 1:23.488. Probably better not to read too much into these times, though.

31' Piquet has improved further to 1:23.852, while Nico Rosberg sets his first flying lap of 1:25.663.

35' This is the Nelson Piquet show! He improves by nearly three seconds, clocking a 1:25.989.

36' It's not often you get to say 'hurrah for Nelson Piquet Jr', but the embattled Brazilian has just completed the first full lap of the session. 1:28.756 isn't great, but it's enough to go top of the pile.

38' If you're confused about the FIA vs FOTA dispute threatening the future of F1, here's a handy Q and A cheat sheet. F1 in crisis: Q and A

40' In comes Massa - still no flying laps a third of the way into the session. This isn't world-class entertainment, it has to be said.

43' Felipe Massa is out on track, but he will probably just do an installation lap and come back in.

45' Sebastien Buemi has a problem with his hydraulics and Toro Rosso mechanics have got his car up on jacks; they are having a poke around.

50' Lewis Hamilton sits in the McLaren garage with his dad. It is a waiting game this morning - a few drivers have had sighters but no flying laps on the board as yet.

55' Sebastien Bourdais talks on his team radio about the problems with the surface. "For sure it's dry, but..." Basically, drivers can go on slicks, which will have no grip, or intermediates, which will get torn up pretty quickly as there is not enough moisture to keep them cool.

57' This race has been completely overshadowed by the potential split looming over F1. FIA chief Max Mosley has attempted to play it down, however, and says that the teams will back down when push comes to shove. Read more here!

59' The session is off to a slow start with a damp track. Tricky conditions for the drivers as it is not a wet session as such - there is just no grip. But they may have to cope with this during qualifying...
