Sebastian Vettel still extended his lead in the 2011 world championship despite losing the marathon Canadian Grand Prix on the very last lap.
"I led every lap until part of the last one," said the disappointed Red Bull driver, who ran off the dry racing line to let McLaren's Jenson Button past mere corners from the chequered flag ahead of third-placed Webber.
"It's not the sweetest feeling," admitted the German, despite pulling out his lead - now over Button - from 58 to 60 points.
It was a marathon day at the Circuit Gilles Villeneuve, following an excruciatingly long red flag delay due to torrential rain.
Button's victory was epic, given his drive-through penalty, a high speed run from the back of the safety car pack, and collisions with teammate Lewis Hamilton and also Ferrari's Fernando Alonso.
As for his clash with Lewis Hamilton, who had to retire, Briton Button said: "I couldn't see anything and I've apologised to him."
"Then, it was really a fight. I got a drive-through for speeding behind the safety car and I had to fight my way through about three times," Button told press after the race.
"Eventually, on the last lap I was chasing down Seb. He ran a little bit wide onto the wet part of the circuit and I was able to take the opportunity and take the win."
McLaren boss Martin Whitmarsh, meanwhile, is hoping the stewards will not issue a post-race penalty after Button tipped Alonso into retirement from the race.
"I think Fernando shut (the door) on him," Whitmarsh said on BBC television, but Spaniard Alonso did not agree.
Hamilton discusses Button crash during rain red-flag
While the sodden spectators waited for the Montreal rain to ease, the latest F1 controversy began to swirl.
The Canadian Grand Prix was red-flagged for a long period while the predicted heavy afternoon rain lashed the circuit.
As the teams stood idle, drinking tea and eating biscuits on the grid with drivers sitting in their cockpits under canvasses, Lewis Hamilton was at the back of the pits speaking about his collision with teammate Jenson Button.
McLaren's Hamilton had to retire from the race after clashing with the team-mate's MP4-26 amid the spray and forcing him against the pitwall.
"What's he doing?" Button exclaimed in the radio, having clearly not seen his countryman through the spray in his mirrors.
Hamilton told reporters: "I don't know if he could see me or not, but he just kept coming over and over," said Hamilton, who later consoled himself with a hug from pop star Rihanna.
Webber's Words On Finishing Third
“I had a few people to pass after the break; it wasn’t too hard until the dry line appeared on the racing line and it was slippery off line. It was then very hard to clear some of the guys, as it meant there was such a narrow window to get down the inside of people," Webber said after the race.
"When you have experienced guys like Michael (Schumacher) and Nick (Heidfeld) to pass, well those guys know what they’re doing, so it becomes even trickier. I decided to roll the dice and go onto the slicks. I was happy to see that not everyone followed immediately, so I had two laps which was enough to bring me back in the game for the podium."
"Then it was a pretty good fight with Michael, we both wanted the same bit of track when we were braking for the chicane, but when JB arrived, he was absolutely flying. Today’s result means plenty of points for the team and it’s a good result, so I’m pretty happy with that.”
