Which Dragon left the British television show Dragons' Den after its twelfth series?

Duncan Bannatyne left the British television show Dragons' Den after its twelfth series.

Bannatyne was one of the original investors when the British series began in 2005. He became widely associated with the show through his direct questioning and his background as a businessman whose interests included care homes, health clubs and hotels.

His departure came after series 12, which was broadcast in 2014. The change was part of a broader evolution in the Dragons' lineup, as the programme regularly refreshed its panel while retaining some established investors. Bannatyne's exit should not be confused with the departure of Theo Paphitis, another prominent early Dragon who left several years earlier.

After Dragons' Den, Bannatyne continued public work connected with business, philanthropy and health. The programme's use of numbered series can make dates confusing, because a series may span more than one calendar year; in Bannatyne's case, the key identifying point is the end of series 12.
