Charles Spencer’s latest book about his sister, Princess Diana, makes a provocative claim regarding her decision to divorce the future king. The revelation centers on an alleged affair between Charles and his valet. The book, titled “Swan Song: Diana, My Sister,” covers Spencer’s interactions with the then-Prince of Wales following Diana’s 1997 death.

Spencer’s account includes lunching with Diana in the 1990s at a London restaurant, where she disclosed her intention to divorce Charles, citing his affection for his valet. Spencer recalls being momentarily silent, noting he knew things were problematic but not to this extent.

Although Spencer doesn’t identify the valet, journalist Tom Sykes highlights Michael Fawcett, known for the “cash-for-honors” scandal in 2021. In this scandal, Fawcett reportedly promised British citizenship and a knighthood to a Saudi billionaire in exchange for donations. Despite police investigations, no charges were made.

There was also an earlier rumor about Fawcett’s alleged relationship with Charles, originating from George Smith, a valet in the prince’s household. Smith claimed to have witnessed inappropriate conduct but later suffered a mental breakdown. Diana reportedly recorded Smith’s account, but the tape is no longer available, according to Paul Burrell, Diana’s butler, during his 2002 trial.

Fawcett sought legal action in 2003 to prevent publications from including his name in reports on alleged misconduct. Charles’ representatives have consistently denied the rumors, with Sir Michael Peat dismissing them as unfounded.

Recent statements from Buckingham Palace caution that grief can “cloud reason” and question Spencer’s motivations for repeating these rumors. Public figures like Piers Morgan criticize Spencer’s claims as disruptive to Charles’ reputation.

The book also delves into Spencer’s contentious exchanges with Charles over the funeral procession for Diana, where Charles allegedly expressed a desire to quickly move past her memory.
