Peter Jones's middle name on BBC's Dragons' Den is David.
His full name is Peter David Jones. Jones is a British entrepreneur and television personality who became associated with Dragons' Den from its earliest British run.
He is particularly linked with consumer products, technology, telecommunications and retail investment. His public profile also includes work outside the programme, including the Peter Jones Foundation and several businesses built or backed during his career.
Middle names are often omitted in television credits and everyday coverage, which makes this fact easy to confuse with another investor's biography. The surname Jones is also extremely common, so the relevant person here is the entrepreneur and Dragons' Den investor, not another public figure with the same name.
