Which British business did Duncan Bannatyne establish before appearing on Dragons' Den?

Duncan Bannatyne established the Bannatyne Group before appearing on the British television show Dragons' Den.

The Bannatyne Group grew into a major operator of health clubs, hotels and spas. Bannatyne built the business after earlier ventures in ice-cream manufacturing and other industries, eventually making fitness a central part of his commercial portfolio.

He joined Dragons' Den as one of its original investors and became known for direct questioning and a strong interest in scalable businesses. His public profile also developed through charitable work and television appearances.

The group is sometimes mistaken for a company Bannatyne merely endorsed. It was his own business organisation and later operated clubs under the Bannatyne brand across the United Kingdom.
