The Duke and Duchess of Sussex are to talk about their decision to step away from the monarchy in a TV interview with US chat show queen Oprah Winfrey, to air next month. Oprah With Meghan And Harry: A CBS Primetime Special has been described by the US television network as an intimate conversation. The interview will be broadcast on March 7.

The news follows the announcement that the royal couple are expecting their second child. According to CBS, Meghan will be interviewed about "stepping into life as a royal, marriage, motherhood" and "how she is handling life under intense public pressure".

She will then be joined by Prince Harry, and the couple will speak about their move to the United States last year and their future plans. The decision to speak publicly comes just over a year after the couple announced they had decided to "step back" from life as senior royals and work to become financially independent. They carried out their final formal royal duties last March.

Ms Winfrey is a personal friend of Meghan and attended the couple's wedding in 2018. It is not known whether Harry and Meghan informed the royal household about their plans to be interviewed. Buckingham Palace declined to comment. Oprah is seen as a "very close acquaintance" of the royal couple and it is said that she had apparently been angling for the interview for some time.

The Duke and Duchess have taken part in video calls from their new home in Montecito in California but they have insisted the focus of attention remained on the causes and charities they were promoting rather than their own personal situation. They have since announced deals with Netflix and Spotify, and started a podcast series, but beyond a brief introduction to their son Archie, they have not revealed any private information.
