Andrea Dovizioso won the last British Grand Prix at Donington Park as the top three riders in the MotoGP World Championship had a race to forget.

The Repsol Honda rider won his first ever Grand Prix in the premier class after Fiat Yamaha duo Valentino Rossi and Jorge Lorenzo both crashed while leading in front of nearly 90,000 fans.

Rossi was able to remount his bike and finish fifth to increase his championship lead over Lorenzo to 25 points but will rue throwing away the chance to claim a stranglehold on another title.

Marlboro Ducati rider and 2007 world champion Casey Stoner also had a bad afternoon as his tyre gamble backfired to leave him in 14th place.

British rider James Toseland took his Tech 3 Yamaha to a sixth-placed finish as British fans said goodbye to Donington ahead of next year's move to Silverstone.

The inclement weather which had blighted the whole weekend again caused drama as Ducati duo Stoner and Nicky Hayden started with wet tyres on a dry track.

However, the rain held off until light showers near the end and Stoner soon found himself at the back of the field as Toni Elias - who qualified eighth - was the surprise leader through the first two laps.

Lorenzo soon took the lead and built an advantage before Elias suffered a high-speed crash when he highsided after drifting onto the wet kerbs at Starkey's Bridge

Lorenzo then crashed out on lap eight after losing the front end at Goddards and despite his frantic efforts to retrieve his bike he was forced to retire.

Rossi appeared set for a routine win but then crashed himself at the Foggy Esses to hand Dovizioso his maiden win ahead of Colin Edwards and Randy De Puniet.

Alex De Angelis was fourth with Toseland set for a career-best fifth until the masterful Rossi somehow clawed his way back past on the final lap.

For Edwards it was a first podium of the year, but the Texan admitted that negotiating the slippery circuit was extremely hazardous.

He said: "That was 48 minutes of hell. I wouldn't wish that race on my worst enemy.

"Every corner you didn't know if you were going to fall off or not as half the circuit was wet and half of it dry. I did not enjoy that at all.

"But I have a new tactic for riding in the wet. I now use a dark visor so you can't see where the wet patches are as everyone rides faster when they can't see where they're going."

Earlier, Hiroshi Aoyama won the 250cc race while Julian Simon strengthened his grip on the FIM 125cc World Championship as he won a rain-interrupted race.

British rider Scott Redding - winner last year - came third on his Blusens Aprilia.

Redding said: "It feels as good as winning did last year.

"I had struggled all weekend and when the race was red flagged I wasn't happy as I didn't want to lose sixth place.

"But when I came in for the second part my team said that as there were only five laps left I had nothing to lose so it was do or die.

"A few people crashed out which helped but I'm delighted with a podium at my home Grand Prix."
