Which entrepreneur founded the Bannatyne Group and appeared as a Dragon on Dragons' Den?

Duncan Bannatyne founded the Bannatyne Group and appeared as a Dragon on Dragons' Den.

Bannatyne began building businesses in areas including care homes and health clubs before becoming a prominent investor and television personality. The Bannatyne Group developed into a major operator of health clubs and spas in the United Kingdom, carrying its founder's surname.

He joined the original Dragons' Den panel and became one of the programme's most recognisable investors. His direct, sometimes combative negotiating style was a recurring feature of the show, especially when entrepreneurs discussed valuations and equity.

The surname can cause confusion because Bannatyne is both the investor's family name and the name used by his business group. The question asks for the entrepreneur, Duncan Bannatyne, rather than the Bannatyne Group or another Dragon who invested in leisure and fitness businesses.
