Which Dragon's Den investor was known by the nickname 'The King of Retail'?

Theo Paphitis was the Dragon's Den investor known by the nickname “The King of Retail.”

Paphitis built his reputation through retail businesses and became associated with major high-street names, including Ryman and Robert Dyas. His commercial background made retail strategy, branding and store operations recurring themes in his Dragon's Den evaluations.

The nickname refers to Paphitis's business career rather than an official title within the programme. Dragon's Den has featured investors from different sectors, so viewers sometimes attach similar labels to Peter Jones, Duncan Bannatyne or other Dragons.

Paphitis joined the UK panel during the programme's early years and became one of its best-known investors. He later left the regular panel, but continued to be identified with retail entrepreneurship and with his work supporting small businesses.
