Princess Kate revealed Prince William's reaction to Prince Harry's memory.

Kate Middleton and Prince William have chosen not to scrutinize Prince Harry's memoir. Instead, the royal couple decided to ask his aides to give them "important things" from him.

The Duke of Sussex criticizes the Prince and Princess of Wales along with the rest of the royal family in his autobiography, which was released last January.

In an extract from Robert Hardman's forthcoming book on King Charles III, it has been revealed that the future King and Queen of England "refused to open the book which had caused so much pain".

"Naturally, people want to hear Prince William's thoughts on the Spear," the royal biographer wrote in The Making of a King: King Charles III and the Modern Monarchy, out on January 18.

"His staff remain adamant that he and the princess refuse to open the book that has caused so much pain," he added, citing a senior aide who said, "none of them have read it."

They reportedly said, “He's a 40-year-old man with the BBC app on his phone so he knows what he's talking about. But he has people like me telling him what else he needs to know. We gave him the necessities."
