Prince William, 43, has long been at odds with his brother, Prince Harry, 41, and Meghan Markle, 44, particularly over their use of HRH titles in private letters, which the 2020 Sandringham agreement forbade. In April 2025, reports said William was angered when Meghan shared a letter from a Ukrainian official addressing her as 'Your Royal Highness'.
Insiders speculated William might strip them of their HRH and possibly Sussex titles when he becomes king to prevent future issues. The intense sibling rivalry has made such a move seem unnecessary, as their own actions have already damaged their reputations, highlighting a surprising twist: in this case, failure is the harshest punishment.
