Peter Jones has appeared continuously on the British programme Dragons' Den since its 2005 launch. He is an English entrepreneur and businessman who became one of the original investors in the BBC series.
The original panel included Peter Jones, Duncan Bannatyne, Rachel Elnaugh, Simon Woodroffe and Doug Richard. Several of those investors later left the programme, while other businesspeople joined in subsequent series. Jones is the notable continuing member of the original line-up.
His on-screen role is associated with assessing companies across consumer products, technology, retail and services. Like the other Dragons, he can make an offer for an equity stake, negotiate terms or decline to invest.
A common mix-up is to identify another long-running Dragon as an original member. Deborah Meaden, for example, became a prominent investor on the programme but joined after the first series. The distinction matters because the question asks specifically about continuous participation from the 2005 launch.
