Which investor joined Dragons' Den after Simon Woodroffe left the original panel?

Theo Paphitis joined Dragons' Den after Simon Woodroffe left the original panel.

Woodroffe, the founder of Yo! Sushi, was one of the investors in the first British series but did not continue as a regular Dragon. Theo Paphitis subsequently joined the panel, bringing a background in retail, branding and business investment.

Paphitis was already known in British business through his ownership and development of retail interests, including Ryman. His arrival helped shape the investor line-up that many viewers associate with the show’s early years.

The timing can be confused with later changes involving other investors, because Dragons' Den has frequently refreshed its panel. The specific sequence here concerns the transition following Woodroffe’s departure from the original UK line-up.
