Earl Spencer, brother of Princess Diana, has claimed King Charles III 'sounded giddily elated' after learning of his sister's death in 1997. The claim, detailed in an extract from his upcoming memoir 'Swan Song: Diana, My Sister,' describes Charles as sounding like a 'lottery winner' during a phone call following the car crash that killed Diana. The book, set for publication next week, is being serialised in the Daily Mail, with the latest excerpts revealing the alleged conversation.

Buckingham Palace has issued a rare rebuttal, stating that the royal family does not comment on books but that the 'pain of fraternal grief can cloud reason, affect judgment and colour memory.' The palace's response suggests it views the claims as potentially damaging to the monarchy's reputation. The book also includes allegations that some palace members were 'relieved' by Diana's death, a claim that has not been independently verified.

Spencer's account describes the emotional toll of Diana's death, including his belief that she suffered from ADHD and Rejection Sensitive Dysphoria. He also claims Diana considered taking her own life but was deterred by her love for her sons. These personal reflections are part of a broader narrative that frames the royal family's relationship with Diana in a critical light.

Representatives of Prince Harry have not commented on the book, while Buckingham Palace has reiterated its stance against commenting on books. Dickie Arbiter, former press secretary to Queen Elizabeth II, dismissed the claims as 'hogwash,' stating that Charles was 'devastated' at the time and that the account is 'not in his character.' Royal commentator Jennie Bond noted that while Spencer's account is his memory, it lacks the 'two sides to a conversation' that would provide a more balanced perspective.

The royal family has continued with public engagements, with King Charles hosting an AI summit and Prince William participating in a beach clean-up in Scotland. These activities contrast with the private family drama surrounding the claims about Charles's reaction to Diana's death. The public's response to the allegations remains uncertain, with some viewing the book as a new perspective and others as an inappropriate intrusion into private family matters.

What remains unknown is whether the full text of Spencer's memoir will provide additional context or corroboration for the claims. The absence of independent verification means the allegations remain unproven. The royal family's response, while firm, does not confirm or deny the claims, leaving the matter open to public interpretation and further scrutiny.
