A royal expert has claimed the major reason Prince William "simply cannot forgive Prince Harry" after the brothers seemingly put aside their differences following the Queen's death earlier this month.
Katie Nicholl, author of The New Royals - Queen Elizabeth's Legacy and Future of the Crown, has claimed William is unlikely to forgive Harry so easily for one major reason.
"William simply can’t forgive [Harry], not just for his behaviour and what he’s done and how he’s done it, but look at how much now rests on William," said on Dan Wootton Tonight.
"He always thought Harry would be his wingman, now he’s doing it on his own. Thank goodness he’s got Kate by his side."
In her new book, Nicholl addresses the deepening divide between Harry and wife Meghan Markle and the royal family.
It comes after Meghan recently gave an interview with The Cut, where she said it takes "a lot of effort" to forgive and hinted that she can "say anything", with some perceiving it to be a thinly-veiled threat to The Firm.
Meghan said that "just by existing" she and Harry were "upsetting the dynamic of the hierarchy" before they stepped down as working royals.
Ms Nicholl meanwhile, said in her book that William and Kate Middleton felt "relief" when Harry and Meghan made the announcement they would be moving to the US, because they felt the "drama was gone".
William also reportedly held a 'summit of aides', which has become known as Amner Summit, to discuss the future of the royal family after Harry's departure.
While there were initial reports that the Sussexes wouldn't meet up with the new Prince and Princess of Wales, the foursome surprised royal fans by uniting to greet mourners on the Saturday following the Queen's death.
