Peter Jones is the only original dragon to have appeared in every series of the UK programme Dragons' Den.
Jones joined the panel when the British version launched in 2005. The original line-up also included Duncan Bannatyne, Rachel Elnaugh, Simon Woodroffe and Doug Richard, but those other founding investors eventually left the programme. Jones therefore became the enduring link between the first series and later generations of dragons.
He is an entrepreneur and investor whose interests have included mobile communications, technology, leisure and media. On the show, he has become associated with asking for precise financial details and examining how a business could scale.
This fact is about appearances across the UK series, not about the number of investments Jones has made. A dragon can appear on screen without reaching a deal, and televised offers can also depend on later due diligence.
