Button and Vettel to start from pit lane

Jenson Button and Sebastian Vettel will start the Canadian Grand Prix from the pitlane.

Both drivers qualified at the rear of the grid, Button suffering a gearbox problem on his first flying lap and Vettel sitting out proceedings as a result of crashing his Toro Rosso in the morning warm up.

Honda decided on Sunday morning to replace the gearbox unit in Button’s RA108 while Toro Rosso had to prepare the spare car for Vettel.
