"If F1 want to speak to me I am keen to listen," said Khan."My ambition is for London to carry on being the sporting capital of the world."

On Tuesday, Red Bull team boss Christian Horner said he was "amazed" Silverstone had given up its contract for the British Grand Prix because it opened up the door for a race in London.
Just over 24 hours later, here is the London mayor saying he is "sure" such an event could happen. Not great news for the British Racing Drivers' Club, Silverstone's owners, the day before the British Grand Prix weekend kicks off on Thursday.
