Hamilton not yet McLaren's de facto no.1 - Whitmarsh

McLaren is not ready to concede that Lewis Hamilton is its best bet for the 2010 drivers' world championship.

At the head of the title standings, Hamilton is 12 points ahead of his teammate Jenson Button, but the Red Bull runners are close behind with a faster car.

But when asked on Tuesday if Hamilton is now recognised as McLaren's title favourite, team boss Martin Whitmarsh answered: "Not yet.

"I'm sure Jenson hasn't given way to Lewis and he will want to win this weekend and move that momentum back in his favour," said the Briton in a teleconference with reporters.
