The Duke of Sussex announced this week he is planning to publish a tell-all book next year that he said will be “accurate and wholly truthful”. He added he will be writing it “not as the prince I was born but as the man I have become”. However, Joe Little, managing editor of Majesty magazine, said the book is likely to have made "hearts sink" within the Royal Family.

       He added Harry will probably have to step up his game to be "even more sensational" than his explosive chat with Oprah Winfrey back in March.

       Mr Little said: “The pressure must be on him to come up with something even more sensational than what we learned from the Oprah interview.

       “It’s hard not to think that Harry would want to redress the balance, as far as he’s concerned, in print, though it’s been done on screen.

       “You would think hearts will continue to sink at Buckingham Palace, Clarence House and Kensington Palace.

       "I suppose in an ideal world they would have liked a line to be drawn after the Oprah revelations.

       "But clearly that isn’t Harry’s way of doing things. And so this won’t have been great news for Harry’s family.”

       In the interview, Harry and his wife Meghan Markle outlined in shocking detail why they decided to quit life as senior royals, with Harry admitting he felt "trapped" and Meghan saying she was left feeling suicidal.

       They also alleged that one unnamed member of the family had asked how dark their son Archie's skin might be before he was born.

       Oprah later clarified that Harry had said it was not the Queen or Prince Philip who made the comments about the colour of Archie's skin.

       Buckingham Palace also quickly responded the Queen was "saddened" by their claims, but added, "recollections may vary".

       8.44am update: Prince William 'un-brothered' Harry as royal feud intensified

       William and Harry have been at odds for years as the Sussexes departure from royal duties and subsequent allegations about life in the Firm lays bare the rift in the family.

       And in January 2020, William turned down an invitation to a gathering as he fumed at his brother, reports claimed.

       The Queen suggested that the family meet up, but Robert Lacey outlined in his book 'Battle of Brothers' that William's "anger" meant he rejected the idea.

       Mr Lacey wrote: "It was a pity that William was now so angry that he was not speaking to him any more. It was as if Harry had become un-brothered.

       “The Queen had suggested the family should gather for lunch before their big pow-wow in the library that afternoon, but (William) refused his grandmother’s invitation.

       “He would obviously turn up at 2pm for the meeting, he said, but he only wanted to talk business.

       “The Prince himself has not confirmed his friends’ speculation that he was so furious with his younger brother that he would not be able to endure the hypocrisy of smiling at him over lunch.”

       8.28am update: 'Diana would never!' Royal biographer slams Meghan and Harry for 'betraying Royal Family'

       Royal expert Tom Bower was asked by a GB News viewer how Meghan Markle compared to her mother-in-law, Princess Diana, and the royal biographer did not hold back. Speaking to Dan Wootton, Bower explained the former Suits star was nothing like Diana, insisting she was “very different” to what the Duke and Duchess of Sussex imagine.

       “Amanda on GB Views asks Tom, ‘What would Princess Diana make of Meghan?’” Wootton began.

       Mr Bower replied: “I do think that’s one of the other fundamental questions.

       “You see, Diana was very, very different to what Meghan imagines she was like and more importantly, what Harry thinks his mother was like.

       “Diana was an unbelievably royal and loyal monarchist. She would never have betrayed the Royal Family.
