Episode 4

Series revealing the lives of the Dragons' Den dragons. How did they make their millions? And what are they really like?

Peter Jones made his money in the telecoms industry and has gone on to become one of the most high-profile businessmen in the UK. With unprecedented access to Peter's business and personal life, the programme follows him as he visits 10 Downing Street for a meeting with the prime minister and spends time at home with his five children. There is also a look at how he made, and why he lost, his first fortune.

The programme also catches up with Peter's investments, which are among the most memorable in the Den. Both Levi Roots and his Reggae Reggae Sauce are household names, but how much money are they making? And Hamfatter, the first band to enter the Den, ended up being able to choose between offers from four dragons. Peter won that battle, and we catch up with the band during their recent UK tour and discover whether their dragon backer has turned them into a profitable proposition.
