Peter Jones was the sole original Dragon's Den investor to appear in every series of the UK programme.
Jones is a British entrepreneur and investor whose businesses have included interests in technology, media, telecommunications and retail. His long tenure made him one of the most recognisable figures in the programme's history.
The original panel changed over time. Duncan Bannatyne, Rachel Elnaugh, Doug Richard, and later Theo Paphitis and Richard Farleigh were among the early investors, but they did not all remain for every series. Jones's continuous presence distinguishes him from the other original dragons.
This fact is easy to confuse with claims about the longest-serving panel members or the first investors to appear. It refers specifically to the original dragon who appeared in every UK series, not to every investor who joined the show later.
