Resolution Criteria:
This question resolves as "Yes" if, by December 31, 2024, official confirmation is received from the British Royal Family, or a representative body thereof, that Prince Harry has been stripped of his royal title.
This includes any formal announcement made by Buckingham Palace, the British Monarchy's official website, or a statement from a recognized authority within the Royal Family or its representatives.
The loss of the title must be explicitly due to a formal decision by the Royal Family or a governing body with the authority to make such decisions, not due to technicalities, legal changes unrelated to the Royal Family's decision, or Prince Harry's personal choice to renounce his title.
If no such confirmation or announcement is made by the end date, the question resolves as "No".
Media reports alone do not constitute sufficient evidence unless they are direct reports of an official statement or announcement as specified above.
Any ambiguity in reports or statements regarding the status of Prince Harry's title should be resolved in favor of a "No" outcome, unless clarified and confirmed by an official source as described above.
"The editorial board for the U.K.’s “newspaper of record,” The Times, said this week that King Charles III should consider stripping his son and daughter-in-law, Prince Harry and Meghan Markle, of their Duke and Duchess of Sussex titles, following the publication of “Endgame,” a highly critical book about the monarchy, written by an author known as their “unofficial mouthpiece.”"
