ISTANBUL, Turkey (CMC) — Fortune favoured Lewis Hamilton and Jenson Button, when Red Bull drivers Mark Webber and Sebastian Vettel collided to pave the way for a McLaren-Mercedes one-two in the Turkish Grand Prix on Sunday.

Hamilton and Button trailed the two Red Bull drivers until the 40th lap, but things became unravelled on the next lap.

Vettel got a run on Webber on the inside going down to turn 12, and had drawn alongside, but as he tried to move to the right to gain the entry line, his right rear wheel clipped the Australian’s left front.

Suddenly, Vettel was spinning wildly down the road and into retirement with a punctured right-rear tyre, and as Webber was forced to run wide, the two McLarens picked their way gleefully through the debris to snatch the lead positions.

“It was quite an eventful race,” said Hamilton, whose grandparents hail from Grenada. “I had a great start, and somehow I thought that I had a better reaction to Mark, but obviously Sebastian passed me.

It seemed the McLaren duo had been handed the race on a platter, but the drama wasn’t over. There was a small amount of rain, but around this time, the McLaren drivers were also told to conserve fuel.

Button sliced into Hamilton’s lead, and got a similar run on him going into Turn 12 on the 48th lap.

But he was on the outside, and as Hamilton hung tough on the inside, they went side-by-side through that corner, as well as Turns 13 and 14.

The two McLarens touched wheels lightly as Hamilton pushed back through into first place going into Turn One, and he was able to open the gap again to score a timely victory as both he and Button eased off to save fuel.
