Peter Jones was the only original investor to remain on the British series Dragon's Den from its first series.
Jones joined the original panel when the BBC launched the British adaptation. His background in business and technology made him one of the programme’s central investors, and he continued appearing as other Dragons joined or departed.
The original panel included several investors who became closely associated with the early programme. However, the panel changed over time, so the phrase “original Dragon” does not mean that every early investor stayed for the entire run. Peter Jones’s continuity is the key fact behind this question.
Viewers sometimes confuse long-serving investors with founding members. Deborah Meaden, Theo Paphitis and James Caan each became prominent Dragons, but they did not all belong to the first panel or remain throughout the programme’s history.
