“SICK SLUR” CLAIM ROCKS THE ROYALS: Earl Spencer’s Explosive Book Allegedly Makes a Stunning Claim About King Charles

Charles Spencer says Diana once told him her husband was 'in love with his valet.' The allegation is now in a published memoir - but it is still second-hand, unproven and tied to a rumor Clarence House forcefully denied more than two decades ago.

Charles Spencer has taken his war of words with King Charles into far more personal territory. In Swan Song: Diana, My Sister, the Earl recounts a private lunch at which Diana allegedly told him she planned to divorce the then-Prince of Wales because, in her words, her husband was 'in love with his valet.'

The line is explosive because it does more than revisit the collapse of Charles and Diana's marriage. It reopens a rumor that consumed royal coverage in 2003, triggered injunctions, forced Clarence House into an extraordinary public denial and was never established as fact.

Spencer has also accused Charles of sounding 'giddily elated' after Diana's death and of later making the remark, 'we'll forget her soon enough' - claims Buckingham Palace has publicly challenged. The result is no longer simply a memoir launch. It is a direct battle over whose memory of Diana becomes part of the historical record.

Read the full analytical breakdown below.

1. THE 'VALET' CLAIM IS IN SPENCER'S BOOK - BUT IT IS NOT PROOF OF AN AFFAIR

The most incendiary new passage is straightforward in its wording but limited in what it can prove. Spencer writes that Diana told him she intended to divorce Charles and then said: 'My husband is in love with his valet.' Spencer says she did not identify the member of staff and that he did not ask who she meant or why she believed it.

That distinction matters. The memoir establishes that Spencer says Diana made the allegation to him. It does not establish that the allegation itself was true, that a romantic or sexual relationship existed, or even that Diana was referring to the man later identified by commentators as Michael Fawcett.

People and The Guardian have both reported the passage as a claim attributed to Diana through Spencer, not as a verified finding. That is the correct evidentiary level. A private statement remembered decades later can be historically interesting and personally damaging without becoming proof of another person's intimate life.

It is also important not to turn the passage into a conclusion about Charles's sexuality. The public record supports only that a claim has resurfaced. It does not support assigning the King a sexual orientation or treating a previously denied affair as established fact.

2. THE OLD MICHAEL FAWCETT RUMOR WAS ALREADY FOUGHT OVER IN COURT AND DENIED BY CLARENCE HOUSE

The reason the line exploded so quickly is that royal watchers immediately connected it to Michael Fawcett, Charles's long-serving former valet and aide. But Spencer does not name Fawcett in the passage, so that identification remains an inference made by the media and commentators.

The background is real. In 2003, allegations involving Charles's household and a former servant became the subject of a bitter legal battle. Fawcett sought an injunction to prevent publication of material he said was false and damaging. The Guardian later won the right to identify him as the person behind the injunction.

Clarence House then took the unusual step of issuing a public denial. Sir Michael Peat, Charles's private secretary, said the allegation about the prince was 'totally untrue' and 'without a shred of substance.' Contemporary Guardian reporting also noted that there was no evidence the alleged incident was true.

That history does not prove Spencer's memory is false. But it means the new memoir is not unveiling a previously confirmed secret. It is reviving an old allegation that was publicly contested, legally sensitive and never substantiated. That is a very different proposition from the viral framing that Charles has suddenly been 'exposed.'
