Do you like the idea of watching Formula One cars zooming around the streets of London at top speeds of 190 miles an hour? Well if you shut your eyes tight and wish long and hard enough, it could be a reality. Despite it representing a mammoth logistical and financial task, and being something of a pipe dream!

It might not be for much longer though, especially if billionaire Bernie Ecclestone has his way. He and Santander enlisted the help of some big guns to promote it. Yes, world champions and top racing driver totty, Lewis Hamilton and Jensen Button joined the celebfest to flash their smiles at this publicity stunt ahead of next week's British Grand Prix at Silverstone.

The boys both consulted on the design of the circuit revealed yesterday. It's complete with ready-made tricky twist, as cars have to squeeze through Admiralty Arch off Trafalgar Square.

And Jenson in particular like the idea of scooting around the monuments and landmarks of the capital.

Jenson Button says: Silverstone for me is a fantastic circuit, a great layout but I think having a race in London would be even more special because racing around the streets of London, for me being very patriotic I think we're going to get a lot of fans out, a lot of British fans out to watch the Grand Prix. "And also the route; go past Buckingham Palace, past Big Ben, Nelson's Column. It would be spectacular"

Celebs like Radio 1Xtra presenter Sarah-Jane Crawford and footballer Rio Ferdinand were put through their paces on the track simulator while Jensen and Hamilton mocked, sorry helped them out!

With 14 corners and a 190mph straight run up to Buckingham Palace, it all looks pretty slick. But what are the chances of it actually happening for real?!?

Well The Times reportedly said Ecclestone's offering a £35m pot for it. And even though former Mayor Ken Livingstone batted the idea away a few years back, Boris Johnson has given a qualified nod of support.
