Rachel Elnaugh left the regular investor panel of BBC's Dragon's Den in 2006.
Elnaugh was part of the programme's original-era panel and became the first woman to serve as a Dragon in the British series. Her departure occurred after the show's early run, as the investor line-up began to change and the BBC introduced different business personalities.
Her exit is part of the programme's broader panel history. Dragon's Den has repeatedly refreshed its cast, meaning that investors familiar to later viewers were not all present at launch. This can make individual departure dates easy to confuse with the dates when replacement Dragons first appeared.
The year 2006 refers to Elnaugh's departure from the regular panel, not the launch of the programme itself. The British series began in 2005 and continued with changing combinations of investors.
