Charles Spencer’s Diana Memoir Brings Fresh Tensions for King Charles

The 9^th Earl Charles Spencer, the younger brother of the late Princess Diana penned a new memoir Swan Song: Diana, My Sister, seems to bring a fresh tension surrounding the royal family and Diana’s death.

The book title Swan Song: Diana, My Sister, is due to be released on September 22, 2026. Charles Spencer presents a personal account of his sister’s life, death and the events that followed her fatal car crash in Paris in 1997.

A disagreement between Prince William and Prince Harry in one of the most discussed section, who were 15 and 12 at the time, should walk alongside the funeral procession behind their mother’s coffin.

According to an excerpt reported from the memoir, Spencer recalls a heated phone conversation with then-Prince Charles. Spencer alleges that Charles expressed anger over Diana’s continued public attention and said, “Rest assured, we’ll forget her soon enough.” The claim is presented as Spencer’s recollection and has not been independently established.

Buckingham Palace issued a response to the claims without discussing the memoir itself. According to its spokesperson, grief can sometimes affect how people remember events and make judgments over time.

Spencer has called the memoir as an extremely personal account anticipated to preserve his memories of Diana and present her story from his outlook. The book is likely to draw further public attention as the anniversary of Diana’s death approaches.
