Diana’s Panorama interview with Martin Bashir was watched by more than 20 million viewers in Britain and became one of the defining moments of her failed marriage to Prince Charles.
It included an admission of an affair and the line that there “were three of us in this marriage”, referring to Charles’ relationship with his now second wife, Camilla Parker-Bowles.
This month, Diana’s brother Charles Spencer said the BBC had failed to apologise for what he said were forged documents and “other deceit” which led him to introduce Diana to Bashir.
The BBC has said the broadcaster is determined to get to the truth about Spencer’s assertions and has appointed John Dyson, one of the country’s most senior retired judges, to lead the inquiry.
Bashir has made no public comment on the situation and the corporation says the journalist, who gained global renown from the interview, is currently on sick leave, recovering from heart surgery and from contracting Covid-19.
Harry and Meghan moved to California after stepping back from royal duties in January and have signed a multi-year production deal with Netflix as part of their plans to be more financially independent.
The source added that the couple had decided to share their property in England, Frogmore Cottage, with his cousin Eugenie but would stay there when they visit the UK.
