Which Dragon left the regular Dragon's Den panel in 2014 after appearing in every series?

Duncan Bannatyne left the regular Dragon's Den panel in 2014 after appearing in every series up to that point.

Bannatyne became one of the original investors when the British programme launched and remained a regular Dragon through its first twelve series. His business interests included health clubs, care homes and hotels, and he was known on the programme for challenging entrepreneurs about sales, costs and valuation.

He announced his departure in 2014, explaining that he wanted to pursue other projects, including charitable and business activities. His exit marked the end of an important early era for the show, although other original investors continued beyond that point.

The wording matters because Bannatyne was not the only long-serving Dragon. Peter Jones also became a central continuing figure, while Deborah Meaden joined later. Bannatyne's distinctive fact is his presence in every series before his departure.
