Peter Jones was the only original Dragon to appear in every series of the British Dragon's Den.
Jones joined the original investor panel when the programme began and remained its longest-serving original Dragon. He is a British entrepreneur whose interests have included consumer brands, technology, media and leisure businesses. On the programme, he is known for examining a pitch’s growth potential, ownership structure and route to market.
The original panel also included Duncan Bannatyne, Rachel Elnaugh and Doug Richard. Other investors joined later, including Theo Paphitis, so the words “original Dragon” and “appeared in every series” identify a specific combination of facts rather than simply naming the longest-serving investor.
Peter Jones’s continued presence helped provide continuity as the panel changed. His tall stature and formal style also made him one of the programme’s most recognisable figures, but the answer is based on his series-by-series participation rather than on appearance or personality.
