Earl Spencer’s upcoming book about his late sister, Princess Diana, is already creating questions about his relationship with Princes William and Harry before the memoir has even reached readers.
The book, Swan Song: Diana, My Sister, is due to be released on Monday, while excerpts have already attracted major attention because of claims surrounding King Charles and the events following Diana’s death in 1997.
According to reports, Spencer recalls conversations and events from the period after Diana’s death and makes serious allegations about the then-Prince Charles. Buckingham Palace has responded by stressing that grief can affect memory, judgment and the way people remember painful events many years later.
The controversy could place William and Harry in an uncomfortable position because Spencer is their maternal uncle, while the person at the centre of the disputed claims is their father, King Charles.
Royal editor Emily Nash suggested that the situation may be particularly complicated for Harry. The Duke of Sussex has maintained a strong public connection with his mother’s legacy, while he has also been attempting to improve his relationship with his father. That could make responding publicly to his uncle’s allegations especially difficult.
William faces a different set of pressures. As heir to the throne, his public role requires him to navigate sensitive family issues while maintaining his responsibilities within the monarchy. Nash noted that the situation could therefore leave William facing difficult choices over how, if at all, he responds.
Harry’s relationship with Spencer has also received attention. Reports say Harry stayed with his uncle at Althorp earlier this year, and other coverage has suggested that the pair discussed the forthcoming memoir. However, reports have differed over how much Harry knew about the book’s contents in advance, with one account saying he was aware of the project but had not read the manuscript.
The timing is also significant because the royal family is approaching the 30th anniversary of Diana’s death in 2027. With both William and Harry continuing to be associated with their mother’s memory in different ways, Spencer’s memoir is likely to keep attention focused on Diana’s legacy.
For now, there is no confirmed public statement from William or Harry about how they view the allegations in Spencer’s book. Their personal relationships with their uncle and father remain separate from the claims made in the memoir, meaning readers should distinguish reported commentary from what the princes themselves have actually said.
