The upcoming Earl Spencer Diana book has triggered a rare response from Buckingham Palace after the late Princess Diana’s brother made a disputed claim about King Charles. In his memoir Swan Song: Diana, My Sister, Earl Spencer recalls an alleged heated phone conversation with Charles shortly after Diana’s death in 1997. Spencer says the then-Prince of Wales told him, “we’ll forget her soon enough,” during an argument over Diana’s funeral procession. Buckingham Palace responded by pointing to the way grief can affect memory and judgment. The memoir is due to be published on September 22, 2026.What Does Spencer’s Book Claim?The central issue is Earl Spencer’s personal account of events surrounding Diana’s funeral. According to extracts published ahead of the memoir, Spencer objected to Princes William and Harry, then aged 15 and 12, walking behind their mother’s coffin.
