Prince Andrew has been accused of making disparaging remarks about Kate Middleton, which reportedly created a major rift with his nephew, Prince William. The claims come from royal biographer Andrew Lownie in his new book Entitled: The Rise and Fall of the House of York.

According to Lownie, the Duke of York’s “nasty” and “unkind” words about the Princess of Wales reflected jealousy over her growing role within the monarchy, particularly after the death of Queen Elizabeth II. The biographer told OK! Magazine that he was surprised by the allegations, describing Kate as “the family’s saving grace.”

Speaking to RadarOnline, Lownie added: “I’d have thought Prince Andrew would respect William as future king, rather than being nasty about his wife.”

Strained ties within the Royal Family

Sources close to the royals suggest these alleged remarks marked a turning point for Prince William, who has long struggled with his uncle’s behavior. Known for his strong sense of duty, William is said to have grown increasingly frustrated with Andrew, especially at a time when the family is under pressure to modernize and maintain public trust.
