Which Dragons' Den investor was known as the founder of Bannatyne Group?

Duncan Bannatyne was the founder of Bannatyne Group.

Bannatyne built the group around health clubs, hotels, and spas, creating one of the best-known leisure businesses associated with a Dragons' Den investor. He joined the BBC programme as a Dragon in its second series and became recognized for his direct questioning and strong focus on the numbers behind a proposal.

The company’s health-club business expanded through acquisitions and new openings. Bannatyne’s public profile also includes charitable work and business writing. His path into business was not limited to leisure: he had earlier worked in several ventures, including an ice-cream business, before developing the group that bears his name.

The name Bannatyne Group can therefore be confused with the title of the television investor himself. The answer is Duncan Bannatyne, while Bannatyne Group is the business organization he founded and developed.
