McLaren Racing CEO Martin Whitmarsh smiles at paddock area Thursday, April 16, 2009 at Shanghai International Circuit in Shanghai, China, where the Chinese Formula One Grand Prix, the third Grand Prix of the season, will be held on Sunday. McLaren chief executive Ron Dennis relinquished all Formula One roles Thursday amid the fallout from a lying scandal that could lead to the team being banned from the world championship. Whitmarsh, who replaced Dennis as F1 team principal in January, will now take on his CEO role and answer to the board on all F1 matters.
