The conversation took place in 2019 after Prince Philip's, along with King Charles to decide what Harry and Meghan's future looked like in the royal family.

Harry continued that sadly in that moment, he didn't believe William which made him reflect on the distance he felt between them. Harry impressed upon the reader that those words were, to them, an incredibly sacred, "universal key" to use in situations of "extreme crisis," when nothing else worked.

There have been a string of many other royal bombshells revealed in the novel, including what the then Duchess of Cambridge thought when he told her and Prince William that he was dating Meghan Markle, Harry's last conversation with the Queen before her death and how Harry believed Diana was in hiding for years. Our full roundup piece of the biggest stories to emerge from the publication.

HELLO!'s royal correspondent, Emily Nash, weighed in on the novel and sharing her thoughts explained: "Harry clearly feels that he has to get his version of events out there. He wants to tell his truth and he's always casting himself as a sort of whistleblower from within the Royal Institution.

"We really need to hear the other side of the story before we can judge this situation. But, whichever way you look at it, Harry appears to be in pain. His family are clearly very sad about what's going on and no one comes out of it looking very good. "
