Duncan Bannatyne left the regular investor panel of Dragon's Den in 2014.
Bannatyne was one of the programme's prominent early investors and became known for scrutinising entrepreneurs' financial assumptions and business plans. His departure marked another change in the rotating panel of dragons that had developed since the series began.
Before television, Bannatyne built businesses in several sectors, including care homes, hotels and health clubs. He also became known for charitable work and public campaigning, which broadened his profile beyond the programme.
The year refers to his departure from the regular Dragon's Den line-up, not the end of his wider business career or every later television appearance. Panel changes are easy to misdate because the programme announces departures around broadcast seasons rather than always matching a calendar year exactly.
