Rubens Barrichello overtakes Briton to triumph in Valencia Jenson Button finishes seventh but ahead of Red Bulls An extraordinary pit-lane blunder by McLaren cost Lewis Hamilton a second successive victory as Brawn GP’s Rubens Barrichello took the chequered flag at today's European grand prix in Valencia. Hamilton, who began in pole, was leading the Brazilian by around four seconds before his second stop on lap 37 but his afternoon came unstuck when McLaren's mechanics failed to have a new set of tyres ready.

"It's been a weekend that I will never forget, especially because after f...
