Sergio Perez got his season back on track with a crushing win for Addax in the GP2 Series sprint race at Silverstone.

The Mexican passed Davide Valsecchi and his iSport team-mate Oliver Turvey in the opening phase of the race and immediately left the rest of the field behind, routinely posting laps more than a second quicker than his rivals to finally cross the line with a margin of 15.7 seconds.

Polesitter Turvey managed to hold on for second, earning himself his first GP2 main series podium. He had become the local crowd's only realistic hope of a home podium after ART's Sam Bird was prevented from taking the start by a mechanical problem.

Turvey's result did not come easily. He saw off Valsecchi without difficulty, but soon found himself under pressure from Racing Engineering's Dani Clos, who had made good progress from sixth on the grid. The Spaniard launched several attacks but never managed to find a way though, and after seeing off a late challenge from Pastor Maldonado (Rapax), settled for third.

Valsecchi, meanwhile, seemed to be struggling for pace and steadily dropped down the order, losing fifth to ART's Jules Bianchi at Abbey with a couple of laps remaining. He hung on to claim the final point for sixth.
