THE Williams duo of Nico Rosberg and Kazuki Nakajima scored a one-two in final practice to end Sebastian Vettel's domination of the build-up to tomorrow's British Grand Prix.

Rosberg finished on top in final practice at Silverstone, and for the 11th time in 24 sessions overall this season, by becoming the first driver to dip under 79 seconds over the two days.

Rosberg, who celebrates his 24th birthday next Saturday, posted a time of one minute 18.899 seconds on his final hot lap in the dying moments of the hour-long run.

It was enough to depose team-mate Nakajima, who has so far looked strong around the Northamptonshire track, by 0.202secs, with the Toyota of Jarno Trulli third quickest, a further 0.024secs adrift.

Vettel, who, along with Red Bull Racing team-mate Mark Webber, was the class act of yesterday's three hours of action, was unable to respond on his final lap, finishing 0.472secs down, even though it was his best run to date.

The Ferrari duo of Felipe Massa and Kimi Raikkonen were fifth and sixth, with Timo Glock seventh for Toyota. The trio were just within a second of Rosberg.

Renaults Fernando Alonso, Webber and Rubens Barrichello in his Brawn GP completed the top ten, with world champion Lewis Hamilton 11th for McLaren.

The 24-year-old, supported this weekend by Pussycat Doll girlfriend Nicole Scherzinger, has so far not faired too badly on a circuit he previously anticipated would not suit his car well.

Hamilton finished narrowly ahead of title leader Jenson Button, who has seemingly struggled to discover the form that has catapulted him into a 26-point lead in the standings, with six wins from seven races.

Languishing in the bottom three were the BMW Sauber duo of Nick Heidfeld and Robert Kubica, 18th and 20th respectively, the latter at the bottom of the pile for the second time in the three outings.

The war between the FIA president Max Mosley and FOTA, meanwhile, has not been lost on the fans as a giant banner hanging from the back of the main grandstand read: 'FOTA Rules! Max Out!'
