Which British Dragons' Den investor is the founder of the fitness chain Bannatyne Health Club?

Duncan Bannatyne is the founder of the fitness chain Bannatyne Health Club.

The Bannatyne Group operates health clubs, spas and hotels in the United Kingdom. Its health-club business grew from Bannatyne's wider entrepreneurial career, which included leisure, care homes and other businesses.

Bannatyne became one of the best-known investors on the British Dragons' Den panel. His on-screen style was often direct, with particular attention to whether a business could expand and whether the entrepreneur understood the numbers.

The name can cause a simple mix-up: Bannatyne Health Club is a business associated with Duncan Bannatyne, while the investor's surname is also used in the wider Bannatyne Group. The chain is not a separate dragon or a Dragons' Den production brand.
