Peter Jones has been the only original investor to appear in every series of the British show Dragons' Den.
Jones is a British entrepreneur and investor who became one of the programme's longest-serving dragons. His business interests have included technology, media, retail and telecommunications, giving him experience across several industries represented by contestants' pitches.
The original British panel changed over time. Investors such as Duncan Bannatyne, Theo Paphitis and Deborah Meaden became strongly associated with the programme, but they did not all serve continuously from the first series onward. That changing line-up is why “original dragon” and “appeared in every series” are not interchangeable descriptions for every familiar panel member.
The distinction also explains why Peter Jones is often treated as the continuity figure of the British edition. This fact concerns the UK programme, not every international adaptation using the Dragons' Den name, whose investors and series histories differ.
