Olympic heroes James Cracknell and Rebecca Romero joined Ken Livingstone at City Hall on Tuesday to launch a fleet of 'back the bid' buses to promote London's campaign to host the 2012 Olympics.
TfL's 'back the bid' bus is part of a publicity campaign demonstrating TfL and the Mayor's commitment to bring the Olympic Games to London in 2012.
The bus is just one of the 40 highly visible buses 'wrapped' in London 2012 branding that will be in service on London streets from the end of September.
"These buses visibly demonstrate London's commitment to host the Olympic Games in 2012 and will ensure that everyone who lives in or visits the capital knows that London is a serious contender," said Ken Livingstone. "This colourful campaign will provide a unique platform to help build support for the bid in the run up to the IOC's final decision next year.
"This is the largest public awareness campaign TfL has ever run. The sheer scale of what TfL is delivering shows the importance that London places on succeeding in this bid."
Bid chairman Lord Coe said: "We are very grateful to TfL for providing this level of support in such a visible manner. This is all part of our campaign to create a growing and lasting image of London as an Olympic city that gets people excited about backing the bid. I want to see our images all over the city and the country to demonstrate to the IOC that we are serious about winning the right to host the greatest event on earth here in London.
"This level of support is phenomenal and will be crucial to the Bid's success. Everyone across London and the UK can do their bit to make our bid for 2012 a winner. That's why we are encouraging the public to register their support and help bring the Games to London."
