Amidst the political wrangling at Silverstone, Red Bull continued to lead the way in free practice for the British Grand Prix as Sebastian Vettel again led a 1-2 for the Milton Keynes-squad in Friday's second session.

As was the case in the opening session of the day, Mark Webber had been the quicker of the two in the early stages of the session before young team-mate Vettel posted the quickest time with a lap of 1min 19.456secs - slightly slower than he managed during the morning.

Webber was just over a tenth of a second behind in second place, despite ending the session parked at the side of the circuit on the run to Stowe after running wide exiting Becketts, with the car losing drive and coasting down the Hangar Straight before coming to a stop with less than ten minutes remaining.

Ahead of the team's home event, Adrian Sutil gave Force India reason to cheer by posting a hugely impressive third quickest time behind the Red Bull duo, although there was again a sizeable gap between the two leaders and third place with Sutil nearly seven-tenths of a second behind. Sutil's session wasn't without any dramas however as he ran over the nose of team-mate Giancarlo Fisichella's car at the end of the session as he returned to the pits.

Kazuki Nakajima was fourth quickest for Williams while Fernando Alonso was fifth quickest despite losing time behind the Brawn of Rubens Barrichello - who wound up sixth.

Lewis Hamilton was seventh for McLaren, with Jarno Trulli, Nico Rosberg and Nelson Piquet Jr rounding out the top ten.

Robert Kubica was eleventh despite BMW being forced to change the engine on his car mid-session, while championship leader Jenson Button could only post the 14th quickest time. Ferrari pair Felipe Massa and Kimi Raikkonen were well down the order in 17th and 18th.
