Andrew Castle, former professional tennis player and television presenter, is the great-grandson of social reformer Annie Besant. He was a national junior champion before moving to the United States on a tennis scholarship at the University of Wichita.

Castle joined the ATP tour in 1986 and made his Davis Cup debut for Great Britain that same year. Over his eight years on the professional circuit, he reached one ATP Tour singles final in 1988 in Seoul and won three doubles titles. His performances in grand slam tournaments were mixed; he reached the mixed doubles final at the 1987 Australian Open with Anne Hobbs and was a semi-finalist in the men’s doubles at the same event in 1988. He was fined most of his prize money for protesting British government tax policy during the 1990 British National Championship final.

After retiring from tennis, Andrew transitioned to a career in broadcasting. He began as a commentator for Sky Sports and later became the main anchor for ITV’s breakfast programme. He also contributes to the BBC’s Wimbledon coverage. Castle's work in television has made him a familiar face in British media. He joined GMTV in 2000, where he remained for a decade. His presenting roles have included coverage of the Aegon Championships, the Davis Cup, and the French Open, earning his team a BAFTA nomination.

In addition to his broadcasting work, Andrew Castle is an engaging and memorable keynote speaker and event host.
