King Charles accused of ‘gaslighting’ by Princess Diana’s brother in dispute over book claims

The long‑running tension between the British royal household and the family of the late Princess Diana has moved into a fresh, public dispute, as Charles Spencer, the princess’s brother, has accused King Charles III of “gaslighting” him over material he says will appear in a forthcoming biography. In a letter obtained by the press and addressed to a leading national newspaper, Spencer, a historian and former editor of The Spectator, detailed what he described as a pattern of denial and distortion by the monarch and senior palace officials in response to queries about passages in his manuscript that relate to the early years of Charles’s marriage to Diana. Buckingham Palace dismissed the allegations as “unsubstantiated” and characterised the letter as an attempt to manipulate public perception.Spencer’s correspondence, dated early August, outlines a series of exchanges that began in the autumn of the previous year, when he first approached the palace seeking comment on a chapter dealing with the couple’s courtship and the events surrounding their 1981 wedding..

According to the letter, palace officials replied that they could not comment on “speculative material” and later, after Spencer provided excerpts, responded with a written statement that “the facts as presented are inaccurate.” Spencer counters that the palace’s rebuttal ignored a substantial body of contemporaneous evidence, including televised interviews, diary entries and testimonies from senior royal aides, all of which he says support his narrative.The crux of the disagreement centres on a series of claims Spencer intends to make about Charles’s behaviour in the first five years of his marriage. He alleges that the future king was aware of, and in some cases encouraged, the press’s intrusive coverage of Diana’s private life, that he engaged in an extramarital relationship with Camilla Parker Bowles while still married, and that he failed to intervene when the media published unverified stories about Diana’s health and mental state. In his letter, Spencer writes that each of these points is backed by documented sources, including a 1993 memorandum from the then‑private ary to the Prince of Wales, a series of letters exchanged between Diana and her confidante James Gilbey, and a set of internal palace memos that were released under the Freedom of Information Act.In response, a senior spokesperson for the royal household issued a brief statement saying the monarchy “takes allegations of this nature seriously” but that “the claims put forward by Mr Spencer are not supported by the historical record.” The spokesperson added that the palace “will continue to engage with authors and historians in a constructive manner, but it will not tolerate attempts to rewrite history without robust evidence.” The statement also warned that any further unfounded accusations could be considered defamatory.Spencer’s accusation of “gaslighting” – a term that describes psychological manipulation designed to make a person doubt their own perception of reality – reflects a broader narrative that has emerged in recent years about the royal family’s relationship with the press and with members of Diana’s own family..

Since the 1990s, several of Diana’s relatives, including her brother and her former bodyguard, have published memoirs that challenge the official version of events presented by the palace. The new claim adds another layer to a saga that has already seen the release of the 2021 documentary The Crown and a series of parliamentary inquiries into the role of the monarchy in media regulation.Legal experts note that the dispute could have implications for both defamation law and the handling of unpublished manuscripts. In the United Kingdom, the defamation defence of “fair comment” requires that the statements be based on facts that are either proven or clearly attributed to reliable sources..

If Spencer’s manuscript includes material that the palace can demonstrate is inaccurate or taken out of context, the royal household may have grounds to pursue legal action. Conversely, the author’s team might argue that the book is a work of historical analysis, protected by the principle of academic freedom, and that the letter itself constitutes a public interest defence.The potential publication date of Spencer’s biography remains uncertain, but insiders suggest that the manuscript is in the final stages of editing and that a major UK publisher has already committed to a spring release. The book is expected to be titled Prince of Wales: The Untold Years and to cover the period from the couple’s first meeting through the early 1990s, a time marked by intense media scrutiny and the eventual breakdown of the marriage..

Anticipation is high, with pre‑order figures reportedly exceeding those of previous royal biographies, reflecting continued public fascination with Diana’s life and the dynamics of the royal family.Public reaction to the letter has been mixed. Some commentators view Spencer’s accusations as a bold attempt to hold the monarch accountable for past actions, arguing that the royal family should be subject to the same standards of transparency as any other public figure. Others see the claims as a continuation of a long‑standing feud between the late princess’s relatives and the palace, suggesting that personal grievances may be influencing the narrative..

Social media platforms have seen a surge in posts referencing both the term “gaslighting” and the broader issue of media manipulation, highlighting the enduring resonance of Diana’s story in contemporary culture.The royal household’s handling of the matter may also affect its ongoing efforts to modernise its image. Since ascending the throne in 2022, King Charles III has sought to present himself as a more approachable and environmentally conscious monarch, while also navigating the legacy of his first marriage. The controversy could distract from initiatives such as the King’s Climate Taskforce and the recently launched “Royal Family Reboot” series of public engagements aimed at rebuilding trust after the fallout from the 2022 documentary about Charles’s relationship with Camilla.Analysts point out that the dispute underscores a delicate balance for the monarchy: preserving the sanctity of private family matters while satisfying a public that demands greater openness..

The institution has historically guarded its internal communications, yet the rise of digital archives and the increasing willingness of former insiders to publish tell‑alls have eroded that barrier. As Spencer prepares to release his book, the palace may be forced to confront a new wave of scrutiny that could reshape how royal history is recorded and remembered.Regardless of the outcome, the episode adds another chapter to the evolving narrative surrounding the late Princess Diana and her family’s quest for a truthful account of her life. Whether Spencer’s manuscript will stand up to the palace’s rebuttals remains to be seen, but the dialogue it has sparked highlights a broader societal debate about the limits of privacy, the power of the press, and the responsibilities of those who hold the nation’s highest ceremonial offices..

The forthcoming biography promises to reignite discussions that have persisted for more than three decades, offering fresh.
