Who was the first female dragon on Britain's Dragon's Den?

Rachel Elnaugh was the first female dragon on Britain's Dragon's Den.

Elnaugh was an entrepreneur and investor who joined the original panel when the programme launched in 2005. She was known for founding Red Letter Days, a company selling experience gifts such as activities and leisure packages.

Her role was significant because she was the first woman to occupy a dragon position in the British series. She appeared in the early run of the programme before leaving the panel, after which Deborah Meaden joined during the third series.

The record is about the British television programme's investor panel, not the entire international franchise. It is also separate from questions about the first woman to make a deal or the longest-serving female investor. Those distinctions matter because different countries introduced female investors at different times and the British panel changed repeatedly.
