HARRY'S REVENGE ON KATE

Prince Harry is once again taking aim at Kate Middleton over her treatment of Meghan Markle

for years now, he's been demanding an apology. "I am patiently waiting for accountability," Prince Harry said upon the release of his scathing memoir, Spare, three years after he and wife Meghan Markle felt they had no choice but to leave the royal fold in 2020. He went on to pointedly call out one unnamed family member: "You know what you did, and I know why you did it. And you've been caught out, so just come clean."

It sounded like he was addressing his father, King Charles. But a source tells In Touch that Harry's words were actually directed toward his brother's wife, Kate Middleton. "They used to be incredibly close, but Harry feels Kate betrayed him by shunning his wife," the source says. The Sussexes retaliated by painting their sister-in-law in an unflattering light, not only in interviews and Spare, but by unofficially cooperating with the authors of Finding Freedom, Omid Scobie and Carolyn Durand. The book is a deeply sympathetic account of Megxit. Now, Endgame, a new book also by Scobie, includes more criticism of the family and Kate. "Meghan admitted to helping him with the last book, so insiders suspect Harry secretly cooperated with the new one as well," says the source. "He wants revenge."
