When Prince Andrew's case looked like it was heading to trial earlier this year, Prince William couldn't take it anymore.
According to Robert Jobson's new book, William at 40: The Making of a Modern Monarch, the dad-of-three went "straight" to Queen Elizabeth, where he told "her calmly and clearly that Andrew’s role in the royal family had become untenable."
"The decision over the Duke of York was very difficult for the Queen and the Prince of Wales," one source told the author. "They were obviously closer to Andrew than his nephew was. He could evaluate just how damaging his uncle was to the long-term future of the Monarchy."
Virginia Roberts sued Prince Andrew for allegedly raping her when she was 17 years old, but he denied the accusations. In January, Prince Andrew was stripped of his titles — a move that was difficult for the Queen and Prince Charles, but it was easier on William, as he was "able to take the emotion out of the situation."
Prince Andrew and Roberts ended up settling out of court, and it's unclear what his future looks like.
"There will be no public role or comeback for York, if the Duke of Cambridge has any input on the matter – and let me assure you, he does. He should be banished, as far as Prince William is concerned," another insider told Jobson.
But it seems like Andrew hopes there's a way he can fulfill his royal duties again. “Prince Andrew does want to participate in the Platinum Jubilee celebrations and to be present at the St Paul’s Cathedral service of thanksgiving and to pay tribute to the Queen’s magnificent 70 years of public service," a royal insider told The Express. “The Prince and Queen do have a close bond. The Queen knows exactly what she is doing. She’s very much in charge."
