LONDON, UNITED KINGDOM — Prince William has declined to comment publicly on Earl Spencer's controversial memoir about Princess Diana, as Buckingham Palace disputes allegations concerning King Charles III.
Prince William has maintained his public silence over a controversial new memoir about his mother, Princess Diana, despite the book prompting a rare response from Buckingham Palace and renewed scrutiny of the Royal Family.
The Prince of Wales declined to answer a journalist's question about the publication during a visit to ActOne Cinema in west London on 22 September 2026. His appearance coincided with the release of Swan Song: Diana, My Sister, written by Diana's younger brother, Charles Spencer.
The memoir revisits Diana's childhood, marriage, death and funeral. It also contains disputed allegations about King Charles III's behaviour following her death in August 1997.
William's decision not to engage publicly contrasts with Buckingham Palace's response to some of Spencer's claims.
Royal commentator Phil Dampier has suggested that William's approach reflects his preference for protecting his family from public controversy, particularly following the serious health challenges experienced by the Royal Family in 2024.
However, William has not publicly explained his decision to remain silent about the memoir. Any connection between his family's recent experiences and his response to the book remains an interpretation rather than an established fact.
William Avoids Questions During London Cinema Visit
The Prince of Wales was visiting ActOne Cinema in Acton, west London, when a journalist asked whether he had read his uncle's newly published book.
William did not respond.
Instead, he continued with an engagement intended to highlight the importance of independent community cinemas.
During the visit, he served popcorn, sold cinema tickets and spoke with visitors and staff. The cinema was celebrating its fifth anniversary, having opened in a converted former library.
His decision not to address the question was reported by several British news organisations, including coverage distributed by the Press Association.
The encounter illustrates a distinction between William's public duties and the private family matters attracting media attention.
His appearance had been organised to recognise a community initiative rather than address royal family disagreements.
Although his silence attracted attention, it did not establish whether he agreed or disagreed with any particular allegation in Spencer's memoir.
Earl Spencer's Memoir Reopens Questions About Diana's Death
Charles Spencer's Swan Song: Diana, My Sister was published on 22 September 2026.
The book offers his personal account of Diana's life, their shared childhood and the events surrounding her death.
Among its most controversial passages are Spencer's recollections of conversations with the then Prince Charles immediately following Diana's fatal car crash in Paris.
Spencer alleges that Charles appeared unusually pleased during one telephone conversation and subsequently suggested that Diana would eventually be forgotten.
Buckingham Palace has challenged the accuracy of these recollections.
Spencer has defended his account, maintaining that the conversations occurred as he remembers them.
The competing accounts have attracted considerable attention because they concern a particularly sensitive period in modern British royal history.
Diana died on 31 August 1997. Her funeral took place on 6 September, with William and Harry walking behind her coffin alongside their father and other relatives.
The decision to involve the two young princes remains one of the most widely discussed aspects of the funeral.
Spencer's memoir revisits his objections to that decision and his recollections of the discussions preceding the ceremony.
His account is a personal memoir rather than an independently established record of every disputed conversation.
That distinction is particularly important when examining allegations about private exchanges that occurred almost three decades ago.
Buckingham Palace Challenges Spencer's Recollections
The palace's response has become a significant development in the controversy.
Royal communications traditionally avoid extensive public discussion of private family disagreements. Nevertheless, Buckingham Palace issued a statement challenging Spencer's account of King Charles's response to Diana's death.
The statement suggested that bereavement could affect the reliability of memories and personal interpretations.
Spencer subsequently defended his recollections in media interviews.
Neither account independently establishes the precise words, tone or intentions involved in the disputed private conversations.
The disagreement highlights the difficulties surrounding historical accounts based on personal memory.
First-hand recollections can provide important evidence about private events, but they may also be contested by other participants.
The controversy therefore involves two separate questions: what Spencer remembers about events in 1997 and how the Royal Family has chosen to respond to his published account in 2026.
William has not publicly entered that disagreement.
His silence should not be interpreted as confirmation of either side's version.
How William Described His Family's Difficult Year
The renewed attention surrounding Diana's legacy comes after William publicly discussed the challenges his family experienced in 2024.
That year, both Catherine, Princess of Wales, and King Charles III announced that they were receiving treatment for cancer.
William subsequently discussed the experience during an appearance on The Reluctant Traveler, the Apple TV+ programme hosted by Eugene Levy.
In the interview, he described 2024 as the most difficult year he had experienced.
The conversation offered an unusually personal account of the pressures associated with supporting close family members during serious illness while continuing to fulfil public responsibilities.
William and Catherine have also spoken about the importance of family life and the welfare of their three children, Prince George, Princess Charlotte and Prince Louis.
These public statements provide relevant background to William's approach to personal privacy.
However, they do not establish why he chose not to answer questions about Spencer's memoir.
Dampier, a commentator who has followed the Royal Family for many years, interprets William's public behaviour as evidence of a preference for maintaining clear boundaries between his family life and his official responsibilities.
He also believes that the experiences of 2024 have influenced William's priorities.
Those conclusions remain Dampier's interpretation, rather than an explanation confirmed by the Prince of Wales.
The Royal Tradition of Remaining Silent
The expression 'never complain, never explain' is frequently associated with the late Queen Elizabeth II and the monarchy's traditional approach to public controversy.
It describes a preference for institutional continuity and restraint rather than responding to every allegation or criticism.
However, royal communications have never followed an absolute rule of silence.
Buckingham Palace's response to Spencer's memoir demonstrates that the institution sometimes considers a public statement necessary.
William has also answered controversial questions on previous occasions.
In March 2021, following allegations discussed during Prince Harry and Meghan's televised interview with Oprah Winfrey, William publicly rejected the suggestion that the Royal Family was racist.
That response showed that he is prepared to address sensitive issues in certain circumstances.
His decision not to comment on his uncle's book therefore represents a choice made in a particular situation rather than proof of an unchanging personal policy.
It also illustrates the different responsibilities of the palace and individual members of the Royal Family.
An official statement can address allegations concerning the monarch, while the Prince of Wales may continue carrying out engagements without publicly discussing the same controversy.
Neither approach necessarily reveals the private views of those involved.
Diana's Legacy and the Next Generation
The publication of Spencer's memoir comes as the thirtieth anniversary of Diana's death approaches in August 2027.
Her life continues to attract international attention, while her sons have taken different approaches to discussing their experiences publicly.
Prince Harry has addressed his childhood, his mother's death and his relationship with the Royal Family through interviews, documentaries and his memoir Spare.
William has generally discussed these subjects less frequently, although he has participated in documentaries and public conversations about Diana and the effects of bereavement.
Both approaches have contributed to continuing public interest in Diana's legacy.
Spencer has said that his new book was written independently and without the participation of either prince.
In interviews following publication, he confirmed that he had spoken to both nephews about the memoir and had sought to respect their privacy.
That additional information is important because William's refusal to answer a journalist's question does not establish that he has avoided all private communication with his uncle.
The public controversy also raises broader questions about the relationship between personal memoirs and the privacy of surviving relatives.
Spencer is entitled to publish his recollections, while other family members may choose not to discuss those accounts publicly.
For William, the immediate public record remains straightforward: he continued his scheduled engagement in London without commenting on the book.
Whether he eventually chooses to address its contents is unknown.
For now, the competing accounts surrounding Diana's death remain publicly disputed, while her eldest son continues his official duties without offering his own interpretation of the controversy.
