In the UK television show Dragons' Den, which Dragon founded the Bannatyne fitness-club chain?

Duncan Bannatyne founded the Bannatyne fitness-club chain and later invested in businesses on the UK television show Dragons' Den.

Bannatyne began his business career in the care-home sector and expanded into other industries before building his health and fitness business. The Bannatyne Group became one of the largest independent health-club operators in the United Kingdom, with gyms, spas and hotels in its portfolio.

He joined the original Dragons' Den panel in 2005 and remained a Dragon until 2014. His straightforward style and strong North East accent made him especially recognisable to viewers. His fitness clubs are sometimes confused with other Dragons’ investments, but the Bannatyne brand was created by Bannatyne himself.

Bannatyne has also written autobiographical books and supported charitable causes. His business interests extended beyond fitness, including care homes, hotels and media appearances.
