Which Dragon was a co-founder of the fashion company Red or Dead?

Theo Paphitis was a co-founder of the fashion company Red or Dead.

Theo Paphitis is a British-Cypriot retail entrepreneur and investor who became a Dragon on the British television programme. He is associated with building and investing in consumer, retail and high-street businesses.

Red or Dead was founded in 1982 by Wayne Hemingway and Gerardine Hemingway. Paphitis became involved with the company and helped develop its retail presence before its sale to Alexon Group in 1999. The brand became known for colourful, unconventional fashion and design.

This fact is often simplified as Paphitis having created Red or Dead himself, but the company was founded by the Hemingway partnership. A precise description is that he was a co-founder or key business figure associated with its development, depending on the source's wording. The answer expected here is Theo Paphitis.
