Australia's Casey Stoner extended his overall MotoGP world championship lead after claiming his fifth victory of the season in the British MotoGP at Donington on Sunday.
The Ducati rider finished ahead of American Colin Edwards, who started from pole position on his Yamaha, with fellow Australian Chris Vermeulen of Suzuki third on a circuit made slippery following earlier rain.
Stoner added to his wins in Qatar, Turkey, China and Catalunya two weeks ago to extend his lead on Italian Valentino Rossi in the world standings after the Yamaha rider crossed in fourth position.
Stoner leads the title race on 165 points, 26 clear of Rossi on 139.
Last year's winner Dani Pedrosa of Spain finished eighth despite leading for the first four laps before Edwards took the lead which he held until mid-race when he took a bend too wide and was overtaken by Stoner.
The 21-year-old Australian got off to a poor start in the wet conditions as he dropped from his starting position of fifth on the grid down to ninth by the first corner.
However Stoner showed all the class that has been expected of him after his early season form, as he quickly made his way through the field to get in position behind Edwards at the halfway mark.
After passing Edwards, Stoner pulled away to finish just over 11 seconds ahead of his nearest rival to stamp his authority on this year's championship title race.
