Sebastian Vettel remains on top of the 2011 world championship despite losing a marathon Canadian Grand Prix to Jenson Bbutton 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 the McLaren man past mere corners from the chequered flag.
