Kirsty Young's castaway is entrepreneur Duncan Bannatyne.

He made his name appearing on the TV show Dragons' Den as a no-nonsense investor with an eye for the bottom line. He made his fortune in nursing homes, health clubs and hotels. Quite something, given that aged 30 he was a deck chair attendant who had been thrown out of the Royal Navy for attempting to throw his commanding officer overboard. He says, 'When you've got a criminal record, no qualifications, no references, the best option is starting your own business - because no one can stop you.'
