Chaos in Canada as Button wins

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.
