Andrew Mountbatten Windsor officially no longer a prince after King Charles issues a legal document

King Charles III has issued a legal document formally stripping his brother Andrew Mountbatten Windsor of the title of prince. The disgraced royal has also lost the designation “his royal highness” after the king issued a Letters Patent, a centuries-old type of document signed with a formal seal that expresses the will of the monarch. An announcement published Wednesday in The Gazette – the U.K.’s official public record – said “THE KING has been pleased by Letters Patent under the Great Seal of the Realm dated 3 November 2025 to declare that Andrew Mountbatten Windsor shall no longer be entitled to hold and enjoy the style, title or attribute of ‘Royal Highness’ and the titular dignity of ‘Prince’.”
