LONDON — Formula One boss Bernie Ecclestone isn't so sure about staging races around London's Olympic Stadium after the Games. A group working in conjunction with F1 was revealed last month to be one of four bidders being considered as future tenants for the east London venue. But plans for a London street race, with cars going past iconic sights in the center of the capital, had already been unveiled in June, and endorsed by British drivers Jenson Button and Lewis Hamilton. “I'd rather (have a race) where we originally planned in central London," Ecclestone said at the Olympic Park Saturday. The proposed route would have a start-finish line on the Mall outside Buckingham Palace, with Trafalgar Square, the Houses of Parliament and London Eye also featuring. “We will work on that," Ecclestone said. “It's a project we are going to try to make happen." — AP
