Nico Rosberg took a comfortable win in the Bahrain Grand Prix after Mercedes team-mate Lewis Hamilton suffered a first-lap collision from pole position.

Hamilton dropped to seventh following a clash with Valtteri Bottas’ Williams at Turn One.

The Brit recovered well to finish third but could not catch Ferrari’s Kimi Raikkonen.

Rosberg’s fifth win in a row gives him a 17-point title lead in the title race.
