Which Dragon's Den investor left the British series after its twelfth series?

Duncan Bannatyne left the British television series Dragon's Den after its twelfth series.

Bannatyne is a Scottish entrepreneur and philanthropist who became one of the programme's original Dragons. His business interests included health clubs, hotels and care homes, and his direct style made him a prominent member of the investment panel.

He departed the programme after series 12, ending a long period as one of its best-known investors. The departure should not be confused with the later exits of other Dragons, because the panel has changed at different points in the show's history.

Bannatyne's television career is only one part of his public profile. He has also written autobiographical books and supported charitable causes. On Dragon's Den, he evaluated pitches for potential commercial returns; outside the programme, his business empire covered several service industries.
