In the British TV show Dragon's Den, which Dragon founded the health-club chain Bannatyne Group?

Duncan Bannatyne founded the Bannatyne Group, a British health-club and spa business.

The group grew from Bannatyne's wider business career and became a major operator in the UK leisure sector. Its clubs typically combine gym facilities with health, fitness and spa services, making the company distinct from a single-site fitness studio.

Bannatyne became a Dragon on the BBC programme and was known for direct questioning about money, margins and the entrepreneur's ability to execute. He left the regular panel after several series, but remained strongly associated with the show's early era.

The company name is sometimes mistaken for a family name attached only to one gym. In fact, Bannatyne Group is the corporate business behind a national chain of clubs and spas.
