Nico Rosberg has won the Italian Grand Prix to move to within two points of reigning Formula 1 champion Lewis Hamilton in the battle for this year's championship.

The German's second victory in row was aided by a poor start from Hamilton, who dropped from first to sixth, before battling back to take second. 

Hamilton retains the championship lead but only marginally with Rosberg having taken a further seven points from the nine point advantage he held at the start of the race in Monza.

Ferrari's Sebastian Vettel took third place ahead of team-mate Kimi Raikkonen.

Red Bull's Daniel Ricciardo and Williams' Valtteri Bottas were fifth and sixth respectively.
