Which British entrepreneur left Dragon's Den after the twelfth series in 2014?

Duncan Bannatyne left the British television series Dragon's Den after its twelfth series in 2014.

Bannatyne joined the programme as one of its investors and became known for his direct questioning and interest in businesses with clear commercial potential. His business interests included health clubs, hotels and care homes, making him one of the most recognisable early Dragons.

His departure came after the twelfth series, ending a substantial period on the panel. The timing is important because several investors left or joined at different points, so series numbers are more precise than simply describing someone as an early or original Dragon.

Bannatyne continued working as an entrepreneur, author and television personality after leaving. He should not be confused with Peter Jones, who remained a long-serving Dragon, or Theo Paphitis, who departed earlier.
