In the British TV series Dragon's Den, which Dragon is known for founding Bannatyne Group?

Duncan Bannatyne is known for founding the Bannatyne Group.

Bannatyne is a Scottish entrepreneur, author and television personality. His business group became associated with health clubs, spas and hotels, giving him a background in operating large consumer-facing businesses before and during his time on Dragon's Den.

He joined the original British panel and became known for direct questioning and a willingness to challenge entrepreneurs over valuations and business plans. The Bannatyne Group expanded the leisure and wellness interests that made his name familiar outside the programme.

The answer is not the name of a Dragon's investment company or a brand he merely endorsed. Bannatyne Group is directly tied to Duncan Bannatyne, while other former Dragons, such as James Caan and Peter Jones, built their reputations in different sectors.
