Which Dragon's Den investor left the British panel after series 12, ending his run in 2014?

Duncan Bannatyne left the British Dragon's Den panel after series 12, ending his regular run in 2014.

Bannatyne was one of the original investors when the British series began in 2005. He built his business career in sectors including care homes, health clubs and hotels, and his direct manner became a familiar part of the programme's early years.

His departure was announced after the twelfth series. Nick Jenkins subsequently joined the panel as a new investor, illustrating how the programme refreshes its cast while preserving the same basic format.

Bannatyne is sometimes confused with Theo Paphitis because both were early dragons and both left before the show's later era. The series number and year provide the clearest identification: Bannatyne's regular appearance ended with series 12, broadcast in the mid-2010s.
