Jenson Button took another small step towards a world title tilt by winning the Turkish Grand Prix in unexpectedly comfortable fashion ahead of his Red Bull rivals.

The Briton disposed on polewinner - and pre-race favourite - Sebastian Vettel after the young German made a mistake on the opening lap, and was never seriously troubled thereafter, stretching out an immediate gap and eventually coming home .... seconds to the good for his sixth win in seven races.

Vettel's race went from bad to worse as his light qualifying weight counted for little. The Red Bull team kept him on a three-stop strategy in a bid to catch Button - and he did indeed close up in his second stint - but the ploy eventually dropped him behind RBR team-mate Mark Webber, with the German 'advised' to settle to third in the closing stages.

Second equalled Webber's best career result, even though the Australian will rue having been caught behind Jarno Trulli on the opening lap, while the Italian gave Toyota something to enjoy after its Monaco nightmare by claiming fourth place.

Nico Rosberg, Felipe Massa, Robert Kubica and Timo Glock all collected points - the Pole for the first time this season - as Rubens Barrichello posted the Brawn team's first retirement and neither McLaren troubled the scorers after another poor show in qualifying. Kimi Raikkonen also left Istanbul without anything to show for his efforts in stifling heat, finishing ninth in the second Ferrari.
