Which Dragon's Den investor joined the BBC panel in series 9 in 2011?

Hilary Devey joined the BBC Dragon's Den panel in series 9 in 2011.

Devey was a British businesswoman best known for founding Pall-Ex, a palletised freight network. Her commercial experience gave her a particular connection to logistics, transport and distribution businesses, although she considered proposals from many sectors on the programme.

Her appointment came after several earlier panel changes and added another high-profile entrepreneur to the show's investor lineup. The timing matters because Dragon's Den has introduced investors in different series, and several later dragons are often incorrectly assigned to the same period.

Devey's tenure was relatively brief compared with some of the programme's longest-serving investors. She later became associated with other television work, but her series 9 Dragon's Den debut remains a precise marker in the show's panel history.
