The Queen was reportedly "disappointed" with Prince Harry over the way he treated her respected royal aide.
Royal biographer Robert Jobson has claimed the 96-year-old monarch was unhappy with the Duke of Sussex, 37, after he told off her royal dresser, Angela Kelly, prior to his royal wedding with Meghan Markle in 2018.
The incident in question was well reported in the lead-up to the nuptials, with Harry rumoured to have lost his temper with Kelly, telling her, "What Meghan wants, Meghan gets", after a dispute over what tiara Meghan would wear on the big day.
Meghan, 40, is said to have wanted to wear an emerald headdress from the Queen's vault but the choice was vetoed by the monarch, with the Duchess instead wearing Queen Mary's diamond bandeau tiara.
