Meghan Markle has been planning tell-all interview with Oprah for two years

Meghan Markle has been planning her upcoming interview with Oprah Winfrey for almost two years, sources tell DailyMail.com.

The Duchess of Sussex originally tried to arrange a televised talk with friend and CBS anchor Gayle King after her son Archie's birth in May 2019 – but was overruled by the Royal Family's public relations machine, the sources claimed.

TV insiders say King and Winfrey have been in talks over a sit-down with the Sussexes ever since, eventually leading to the 90-minute interview set to air on CBS March 7.
