Which Dragon's Den investor became a dragon after replacing James Caan in 2011?

Hilary Devey became a Dragon's Den investor after replacing James Caan in 2011.

Devey was a British businesswoman best known for founding Pall-Ex, a palletised freight network. Her business background in logistics gave her a different profile from several other investors on the panel, whose careers included retail, property, fashion and technology.

She joined the programme for its ninth series, taking the place vacated by James Caan. Her tenure lasted for one series before she left the panel to present other television projects, including The Intern.

This appointment is distinct from later changes involving Kelly Hoppen and Sara Davies. Those investors joined at different points, so identifying the year and the departing dragon is essential when comparing the show's changing line-ups.
