Which Dragon left the regular investor panel of the British show Dragon's Den in 2014?

Duncan Bannatyne left the regular investor panel of the British show Dragon's Den in 2014.

Bannatyne was one of the original Dragons when the BBC programme launched in 2005. He became known for a direct questioning style and for investments made across a range of businesses presented by entrepreneurs. His departure came after many years on the panel, making him one of the most recognisable early Dragons.

Outside television, Bannatyne built the Bannatyne Group, which operates health clubs, hotels and spas. He also became known for charitable work and appearances on other television programmes. These activities are separate from his role as an investor on Dragon's Den, although both contributed to his public profile.

The year 2014 identifies the end of his regular tenure, not the end of the programme itself. Dragon's Den continued with changing panels, and Peter Jones remained associated with the show after Bannatyne's departure.
