Jenson Button was supposed to thrill fans behind the wheel of a McLaren-Mercedes F1 car at the 2011 Goodwood Festival of Speed this weekend - but a jet-ski injury meant he actually ended up driving a road-going supercar instead.

Inarguably Saturday's greatest draw at the event affectionately referred to as the world's greatest motorsport-themed garden party, Button had been due to climb into the cockpit of team-mate Lewis Hamilton's title-winning 2008 McLaren MP4/23 to take it for a whirl up Goodwood's legendary hill.

However, after sustaining a leg injury during jet-ski filming for the BBC last week, in order to avoid aggravating it ahead of his home race at Silverstone next weekend, the 2009 F1 World Champion instead took to the course in the new McLaren MP4-12C road car.

Button insisted there is no danger of his not being fit to compete in the British Grand Prix.
