Peter Jones has been a dragon on every series of the UK show Dragon's Den.
Jones joined the original panel when the BBC programme began in 2005 and remained part of the regular cast across the show's subsequent series. His continuing presence made him the longest-serving original dragon and a defining figure in the UK version.
He is a British entrepreneur and businessman whose interests have included mobile communications, technology, leisure and media. On Dragon's Den, he is known for examining a pitch's commercial potential, ownership structure and plans for growth before deciding whether to invest.
Other major dragons have served for several years but have not appeared in every series. Duncan Bannatyne, Theo Paphitis and James Caan were important early panel members, yet each eventually left the programme. Jones's uninterrupted tenure is therefore the specific distinction asked about here.
