King Charles ‘Worried’ Over Prince Harry’s Next Media Moves, Fearing Duke Is ‘Siding with the Enemy’ on Diana Documentary

King Charles III is reportedly harboring profound apprehension over Prince Harry’s prospective media ventures in the United Kingdom, amid mounting reports that the Duke of Sussex is exploring a high-profile documentary commemorating the upcoming 30th anniversary of Princess Diana’s passing.

Palace anxieties have been sharply reignited following the publication of Earl Spencer’s controversial memoir, Swan Song: Diana, My Sister, which leveled explosive personal accusations against the monarch. Having previously weathered the institutional fallout from Harry’s memoir Spare and the Sussexes’ Netflix docuseries, the Firm is bracing for renewed public scrutiny just as the Duke establishes his presence back in Britain.
An insider speaking to Closer magazine revealed deep-seated unease regarding Harry’s alignment with his mother’s side of the family:
“He loves his uncle dearly and openly admires him for having the courage to take no prisoners and fiercely defend Diana’s legacy. There’s so much bad blood with Diana’s side of the family, of course, it feels like Harry is siding with the enemy. Only the Lord knows what they’re planning together, but the King is bracing for the worst.”

Industry reports indicate that while Prince Harry has engaged in exploratory conversations regarding a potential 30th-anniversary commemorative project, Prince William was similarly approached with lucrative pitches but summarily rejected every overture, choosing strict institutional loyalty over public storytelling.
Addressing the controversy during an appearance on CBS Mornings, Earl Spencer maintained that Harry had zero editorial involvement in his explosive book: “I didn’t tell any of the family until just before it was released publicly as a thing. I didn’t want anyone to think, particularly with Harry, who people know I had to stay in the summer, that he was in any way involved in this. It was important to me that they weren’t.” Despite the Earl’s clarification that he has communicated with both nephews since the book’s September 22 debut, Harry’s perceived alliance with the Spencer camp continues to stoke deep mistrust within the royal household.
