Earl Spencer has claimed in his upcoming memoir that King Charles III "sounded giddily elated" upon learning of Princess Diana's death. The claim, detailed in excerpts from his book *Swan Song: Diana, My Sister*, suggests the then-Prince of Wales showed little emotion during the tragic event. Buckingham Palace has denied the allegations, calling them "baseless."

Spencer, who previously vowed never to profit from his sister's death, is now set to make millions from the memoir. The book includes personal accounts and criticisms of the royal family, including claims that Charles was cold-hearted and unemotional. Some of his statements have been met with skepticism, with critics calling them sensational.

The memoir also touches on other royal family members, including Prince Harry, with Spencer sharing a seven-word message he allegedly gave to the prince during Diana's funeral. These claims have sparked debate about the monarchy's public image and the role of family members in shaping historical narratives.

Spencer has defended his claims in interviews, insisting they are based on personal experience and truth. The royal family has not commented further, leaving the controversy open to public interpretation.
