Which British Dragons' Den investor was born Duncan Walker Bannatyne?

The British Dragons' Den investor born Duncan Walker Bannatyne is Duncan Bannatyne.

Bannatyne was born in Clydebank, Scotland, in 1949. His middle name, Walker, is part of his birth name, while Duncan Bannatyne became the public and professional name used throughout his business and television career.

The detail is useful because the programme's investors are usually identified by short professional names rather than full birth names. It should not be confused with the surnames of other Dragons, many of whom also built public identities around their businesses.

Bannatyne became wealthy through several ventures, including care homes and later health clubs. He served as an investor on Dragons' Den and became one of the programme's most recognisable personalities. Beyond television, he has written autobiographical books and supported charitable causes, especially those connected with children and health.
