Which Dragon founded the health-club chain Bannatyne Fitness?

Duncan Bannatyne founded the health-club chain Bannatyne Fitness.

Duncan Bannatyne is a Scottish entrepreneur and philanthropist who built businesses in several sectors, including care homes, hotels and health clubs. Bannatyne Fitness became one of the most recognizable names associated with his business portfolio and later operated clubs across the United Kingdom.

He joined the panel of Dragon's Den and became known for direct questioning about investment, ownership and business performance. His personal name is part of the chain's branding, making this one of the clearest links between a Dragon and a company he founded.

Bannatyne Fitness is sometimes called Bannatyne Health Club in ordinary usage, but Bannatyne Fitness is the business name most directly associated with the chain. It should not be confused with businesses funded by Bannatyne on the programme.
