Earl Spencer, brother of Princess Diana, has claimed in his new memoir that King Charles III sounded “giddily elated” after the death of his sister in 1997. The allegations, detailed in the book *Swan Song: Diana, My Sister*, suggest Charles was unusually joyful following the tragic event. This claim has sparked renewed debate about the royal family's response to Diana’s death.

Buckingham Palace has dismissed the claims as “unfounded” and has not commented further. The memoir, published nearly three decades after Diana’s passing, includes several personal accounts of the royal family. Spencer’s book also touches on the dynamics of Charles and Diana’s marriage, offering a deeply personal perspective.

The claims have drawn criticism from some royal insiders, including former royal butler Grant Harrold, who has dismissed Spencer’s allegations as unfounded. Despite the controversy, the book continues to generate significant public interest.

The royal family remains silent on the matter, with no official response issued. The allegations highlight the ongoing fascination with the late princess and the complex relationships within the royal household.
