In a dramatic turn of events, the British Royal Family finds itself at the center of a deepening rift, with Prince Harry demanding apologies from King Charles and Prince William for the treatment of his wife, Meghan Markle. This standoff casts a shadow over the upcoming 75th birthday celebrations of King Charles, with Harry making it clear that he will not participate in any family events until his conditions are met.

The Duke of Sussex's stance is rooted in a series of grievances, which he believes warrant a formal apology from the senior royals. According to royal author Angela Levin, Harry is adamant about not engaging with his family unless they "apologize to Megan profusely." This demand stems from what Harry perceives as unfair treatment towards him and Meghan during their time as senior royals.

The situation is further complicated by the publication of Harry's memoir, "Spare," earlier this year, where he made several damaging claims against his family, including his father and brother. These revelations have only widened the gap between Harry and the rest of the Royal Family.

Despite the public nature of these disputes, a spokesperson for the Duke and Duchess of Sussex has refuted claims that they declined an invitation to King Charles's birthday. They clarified that there had been "no contact" regarding an invitation, indicating a deeper level of estrangement.

Royal expert Richard Fitzwilliams notes that reconciliation seems a distant prospect, with the rift running deep and personal. He suggests that it could take years for any form of reconciliation to occur, if at all. This sentiment is echoed by Levin, who believes that King Charles is particularly annoyed by the Sussexes' behavior and the demands they are making.

The absence of Prince Harry and Meghan Markle from the upcoming royal celebrations is not just a personal family matter but also a public indication of the ongoing tensions within the British monarchy. As King Charles prepares to celebrate his 75th birthday, the family rift underscores the challenges he faces in his reign, with the "unmentionables" - Harry and Meghan - becoming a persistent and unresolved issue.
