Championship leader Casey Stoner produced another dominant display as he won the British MotoGP at a soggy Donington Park.
The Ducati rider came home ahead of pole sitter Colin Edwards and Suzuki's Chris Vermeulen to earn his fifth win of the season.
Valentino Rossi, Stoner's nearest championship rival, was fourth and now trails him by 26 points. Vermeulen's team-mate John Hopkins came home in fifth.
VerItalian title rival and former world champion Valentino Rossi could not match the 21-year-old Ducati rider's speed on the slippery Donington circuit and finished off the podium in fourth place.
Stoner, 14 points clear before the weekend, now has 165 points to Rossi's 139.
Rossi's Yamaha team mate Colin Edwards was second, 11.768 seconds behind Stoner, with Australian Chris Vermeulen third for Suzuki.
Texan Edwards had started on pole position and Stoner's success maintained a season-long jinx for any rider starting in the top slot, with the last winner from pole dating back to Japan last September.
