A spectacular late charge by Jenson Button saw him emerge on top of a rollercoaster – and rain affected - Canadian grand prix.
Button claimed his first victory of the season in a magnificent fashion as he manoeuvred his McLaren from the back of the pack all the way to the top of the podium, punishing race and championship leader Sebastian Vettel on the last lap after he buckled under pressure and went wide on a slippery Montreal circuit.
But it was his team mate Lewis Hamilton that again caught the attention of both spectators and officials after he tried to force his way to the front after qualifying a disappointing fifth. His ruthless driving that was also seen in Monaco two weeks ago was short-lived as he crashed out after a collision with Button.
The 26-year-old was also in the wars with Red Bull’s Mark Webber, Mercedes’ Michael Schumacher and eventually his team mate, with Button proclaiming “What is he doing?” as the two McLaren’s came together.
Kamui Kobayashi of Sauber provided audiences with the last flash of entertainment in a race that lasted more than four hours as he lost out to Ferrari’s Felipe Massa on the final straight for a photo finish.
