How did he make his millions? In 1978, after a spell in the navy, he bought an ice-cream van for £450. By the mid-80s he had his own business, Duncan's Super Ices, which he sold to fund a chain of nursing homes. Interests now include a casino, a hotel, and his Bannatyne Fitness health club chain (annual turnover £30 million).
The secret of his success? His self-assurance showed itself early - at 19 he threw his commanding officer off an aircraft carrier for a £5 bet. Numerous sultry portrait photos in his new autobiography endorse his claim that 'modesty is not a quality required by an entrepreneur'. However, his self-professed 'computer-like ability with numbers' was apparently invaluable.
