Red Bull's Sebastian Vettel ended Jenson Button's run of success at the British Grand Prix.
As Button was only able to finish sixth, Vettel's victory ahead of his team-mate Mark Webber and Button's Brawn stablemate Rubens Barrichello hinted that this year's world championship might not be entirely settled yet.
Vettel put controlled the grand prix from the outset - striding away from his lighter rivals at a staggering rate in the first stint. Consistently one second per lap quicker, he was 20 seconds clear of the closely-matched Barrichello and Webber by the first stops.
While Vettel cruised to his third career win, Webber completed Red Bull's perfect day by squeezing ahead of Barrichello as he emerged from his first pitstop, which he made a lap later than the Brazilian.
Button was never a factor in his home race. Boxed in behind the slow-starting Jarno Trulli off the line, he completed the first lap in eighth and stayed there for most of the afternoon. Only by running longer at his last stop was he able to jump ahead of Trulli's Toyota and Kimi Raikkonen's Ferrari.
