McLaren driver Jenson Button has admitted that he hopes the consultation on closed-road motor sport events announced by the government could bring a London Grand Prix closer to fruition.

Button said that he was fully behind the idea of a London race when it was first announced, describing the prospect of a grand prix in the streets of the capital as "mind-blowing".

"When I first saw the plans for a London Grand Prix I knew they were ambitious, but fantastic," Sky Sports News quotes Button as saying. "The thought of a race through the capital's streets was only a dream when they initiated the project, but this week's changes to the law bring the idea a step closer to reality.

"When you really picture what it would look like it's truly mind blowing. You could create such a unique grand prix through the streets of London - the roads are naturally very wide and long, so straightline speeds would be high, and you could create a real blend of corners.

"When you combine all of that with the world-famous monuments that would feature in the backdrop you can see why it would be an awesome addition to the calendar."

Button finished ninth in last year's drivers' championship.
