Dennis: Hamilton doesn't need Kovalainen's help

LONDON: McLaren boss Ron Dennis has rebuffed former champion Jackie Stewart for suggesting that Heikki Kovalainen must do more to help teammate Lewis Hamilton win the Formula One title.

"The fact is that Sir Jackie retired from motor racing in 1973, which is 35 years ago, and the sport has moved on in that time," Dennis said on Sunday in a response to comments made by Stewart after last weekend's German Grand Prix.

"Jackie's suggestion that Lewis' world championship campaign depends on Heikki's assistance presupposes that Heikki's task is to drive in support of Lewis - and that simply isn't the case," said Dennis.
