FORMULA ONE: Jenson Button secured arguably the greatest win of his Formula One career at the end of an epic Canadian Grand Prix.

It was a rain-hit race that had everything, but it boiled down to the last lap just as the clock had also hit the two-hour limit.

Reigning champion Sebastian Vettel was hounded into making an error by Button, sliding wide at one stage to open the door, with the 31-year-old needing no second invitation.

Button then made it to the line for a sensational victory, the tenth of his career, and first since last year’s Chinese Grand Prix now 14 months ago.

An emotional Button described the win as possibly the best of his career.

“I don’t know what to say - if I hadn’t won I would still have enjoyed the race immensely, but it was a fantastic win,” he said.
