Britain's Jenson Button won the Bahrain Grand Prix on Sunday for the Formula One championship leader's third victory in four races this season.

The Brawn GP driver's success at Sakhir dashed Toyota's hopes of a breakthrough first win after the Japanese manufacturer had started with both their cars on the front row for the first time.

Germany's Sebastian Vettel was second for Red Bull with Toyota's Italian Jarno Trulli finishing third from pole position.
