Sources: 105. Developments: 2. Earl Spencer has released his memoir, ‘Swan Song: Diana, My Sister’, which provides critical accounts regarding the British Royal Family. The book chronicles Princess Diana’s early life, her marriage to King Charles III, and the aftermath of her death in 1997. Spencer includes controversial claims involving King Charles III, alleging the King displayed callous behavior following the 1997 accident. He recounts a telephone argument where the then-Prince of Wales allegedly stated, ‘You can rest assured! We will forget her very soon!’ Spencer also described the King as sounding ‘giddily elated’ or ‘euphoric’ during a call following the fatal crash. Buckingham Palace has responded by suggesting that the ‘pain of grief may have clouded’ Spencer’s judgment and memory. Adding to the conflicting narratives, Princess Diana’s former butler, Paul Burrell, has publicly disputed Spencer’s account, describing the King as being visibly shaken, pale, and frightened. Legal tensions have also escalated with journalist Piers Morgan, who has vowed to sue for ‘defamatory lies’ regarding Spencer’s claims about his editorial role. New developments have further intensified scrutiny of the monarchy. Prince Harry and Meghan, Duchess of Sussex, are reportedly planning a documentary or film about Princess Diana to coincide with the 30th anniversary of her death in 2027, a project said to cause significant distress for Prince William. Additionally, newly surfaced diaries from Diana’s mother, Frances Shand Kydd, contain harsh criticisms of the monarchy, describing the institution as being defined by ‘emotional hardness and selfishness.’ ## Claims - Charles Spencer claims King Charles III sounded ‘giddily elated’ upon hearing of Princess Diana's death.
