Deborah Meaden joined the British Dragons' Den panel in series 3 after Rachel Elnaugh left.
Meaden is an English businesswoman and investor whose career includes work in family entertainment, leisure and retail. Her arrival gave the programme a new investor with experience in consumer-facing businesses and commercial management.
Rachel Elnaugh was one of the original dragons in the first series. After Elnaugh's departure, Meaden became a long-running and highly recognisable member of the panel. She is associated with a direct negotiating style and with investments in a range of consumer products and services presented by entrepreneurs.
The timing is an important part of the fact. Meaden was not an original-series dragon: she entered during the third series. Names such as Kelly Hoppen and Sarah Willingham are also former dragons, but neither was the investor who replaced Elnaugh at that point in the show's history.
