Which Dragon joined the UK television show Dragons' Den in its third series?

Deborah Meaden joined the UK television show Dragons' Den in its third series.

Meaden became one of the programme's best-known investors after entering the panel in 2006. She brought experience from family entertainment businesses and later developed a broad investment portfolio, making her a prominent figure in British business television.

Her arrival followed the first two series, in which the panel included Peter Jones, Duncan Bannatyne, Rachel Elnaugh, Doug Richard and Simon Woodroffe. Meaden's long tenure means she is often associated with the show's established era, although she was not part of the original series-one lineup.

On Dragons' Den, Meaden evaluates entrepreneurs' businesses by examining factors such as sales, margins, intellectual property and ownership. A televised offer is not automatically a completed investment: the proposal must usually pass further checks and negotiations after the pitch.
