Duncan Bannatyne is the former stoker in the Navy who built up his own business empire and is now a star of the TV series Dragons' Den. 

As Duncan Bannatyne reached thirty, he was still living the life of a beach bum in Jersey.  Fearing that he was about to become the oldest swinger in town, and anxious to settle down with his partner, he realised that what he needed to do was become a millionaire.  Five years later he was. He is now worth over £300 million.

Duncan Bannatyne's first book, Anyone Can Do It, was the bestselling business autobiography of 2006 and was followed by Wake Up and Change Your Life. His latest book, How to be Smart with Your Money, is published by Orion in 2009.
