Duncan Bannatyne left Dragon's Den in 2014 after appearing from its second series.
Bannatyne is a Scottish entrepreneur whose business interests included health clubs, hotels, care homes, and media. He became known on the programme for direct questioning and a willingness to challenge entrepreneurs over valuations and profitability.
He joined the Dragon's Den investor lineup after the first series and remained a prominent member of the panel for many years. His departure was part of the continuing turnover among the programme's investors, rather than the end of the Dragon's Den format.
Bannatyne has also been involved in charitable work and public campaigns, and he received an OBE for services to charity. His long appearance on the show is sometimes confused with the tenure of Theo Paphitis, another former Dragon who left at a different time.
