The Turkish Grand Prix - in pictures

Sebastian Vettel starts from the front of the grid at today's Turkish Grand Prix, maintaining his 100% record in qualifying this season. The German has already opened a 21 point lead over Lewis Hamilton, his nearest rival in the drivers' standings.

Into the opening corners they go and Vettel makes a clean start. Meanwhile, Nico Rosberg jumps ahead of Mark Webber to claim second place.

Button and Hamilton engage in a thrilling duel. Hamilton eventually utilises the DRS (drag reduction system) to shoot past Button on turn one of lap seven Photograph: Dimitar Dilkoff/AFP/Getty Images

Webber earns revenge on Alonso through turn 11 on the 51st lap. Once again, the deployment of DRS allows for a smooth manoeuvre, although Alonso almost reclaims track position on the subsequent pit-straight Photograph: Paul Gilham/Getty Images

Button's three-stop strategy is back-firing. He's demonstrably slower than all those with fresh tyres and has little hope of holding onto fourth place. First he's caught by his team-mate Hamilton, then by Rosberg. He's now down in sixth - the same position from which he started Photograph: Leonhard Foeger/Reuters
