The new Prince of Wales "just cannot forgive" his brother Prince Harry for the way he has behaved and the trouble he has caused for the family, claims a royal author.
While William and Harry did put on a united front at Windsor Castle last weekend to greet well-wishers following the death of the Queen, it is reported that their remains a serious rift between the once close brothers.
Since leaving the UK and setting up home in the United States, the Sussexes have spoken regularly to American media where they have been critical of the Royal Family.
And Katie Nicholl, author of the book 'The New Royals' which discusses the next generation of the Royal Family, says that William cannot just put all this to one side and forget it.
In one explosive interview with Oprah Winfrey, Harry claimed that he had to break the cycle and bring his children up away from the public glare that the Royal Family is under while Meghan alleged she received a racist comment from a member of the family who she did not name.
Ms Nicholl said, while speaking on Dan Wootton Tonight: "Ultimately William just cannot forgive his brother, 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! He always thought Harry would be his wingman, now he’s doing it on his own."
Ms Nicholl said that the friction between Harry and the other royals was a strain on the Queen.
She claimed the Queen was "exhausted" by her attempts to "forge a reconciliation" between the brothers.
"It’s incredibly sad that the twilight years of her reign were marred by this awful family rift that doesn’t show any sign of being healed," she stated.
Among quotes in the book are one from a close family friend who said the Queen "was very hurt" by the whole matter, saying "I don’t know, I don’t care, and I don’t want to think about it anymore."
Ms Nicholl also gives details of a "15-minute" meeting between Harry and his father the King, where Harry suggested a mediator to try to help repair their damaged relationship.
She believes that Harry will now feel remorse at not attending the Queen's Balmoral weekend sleepover for her grandchildren and great grandchildren at the end of August.
