Peter Jones was the only original Dragon's Den investor to remain on the panel through the show's long run.
Jones was part of the original five-investor line-up when the British programme launched in 2005. The other original dragons were Duncan Bannatyne, Rachel Elnaugh, Simon Woodroffe and Theo Paphitis. Over subsequent series, the panel changed as investors joined and departed, while Jones continued as a central member.
He is a British entrepreneur and investor with interests that have included mobile communications, leisure and technology. On the programme, he is known for examining commercial potential, ownership percentages and the practical route from a pitch to a scalable business.
This question concerns the original panel, not every investor who appeared in later series. Deborah Meaden, for example, became one of the programme's best-known dragons but was not part of the original five. Peter Jones is therefore the unique answer among the initial line-up.
