Lewis Hamilton confessed he apologised to Kimi Raikkonen after their race-ending crash during the Canadian GP but refused to admit he was to blame for their pit-lane prang.

The accident occurred in unusual circumstances on lap 19 of the race when Hamilton's McLaren collided with Raikkonen's stationary Ferrari at the end of the pit-lane.

Raikkonen, along with the BMW of Robert Kubica, was prevented from rejoining the race by a red light that Hamilton either did not see or did not see in time to avoid the collision.
