Kirsty's castaway this week is the former England cricketer Andrew 'Freddie' Flintoff.

One of the best players of his generation, he was part of the England team that won the Ashes in 2005, a year that marked his sporting coming of age. On the strength of that historic victory he was awarded an MBE for services to the game, and the public voted him BBC Sports Personality of the Year.

Barely out of his pram when he picked up a cricket ball he turned out to bat for an under-14 match when he was just six years old. His debut was not in crisp cricket whites, but in a second hand Manchester United tracksuit, setting the tone for someone who's made a habit of doing things his way. Not least at a 10 Downing Street reception when, somewhat the worse for wear, he weaved into the cabinet room, plonked himself down in the PM's chair and knocked back yet another bottle of beer.

Since retiring from the game he's had a go at heavyweight boxing and won the bout. One area where he hasn't come out on top: his sons never listen to his cricket coaching tips.
