Princess Diana's brother Charles Spencer says King Charles 'gaslit' him over memoir claims

Princess Diana's brother, Earl Charles Spencer, fired back at Buckingham Palace after the royal household questioned his recollection of a conversation with King Charles III, saying he was being "gaslit" by the monarch.

Earlier this week, The Daily Mail published an excerpt of Spencer's upcoming memoir, "Swan Song: Diana, My Sister," in which the king's former brother-in-law described having a heated conversation with Charles after Diana's death.

In the excerpt, Spencer alleged that Charles said, "We’ll forget her soon enough!," regarding his ex-wife during their exchange.

Buckingham Palace later responded to Spencer's claims, disputing the earl's account of the conversation and suggesting that grief may have affected his memory of events surrounding his sister's death.

KING CHARLES DRAWS ‘LINE IN THE SAND’ WITH PRINCE HARRY, MEGHAN MARKLE AFTER COUPLE CAUGHT OFF GUARD: EXPERT During an interview with The Mail on Sunday, Spencer took issue with the palace's response.

"It is not every day you wake up to find you've been gaslit by the king," he said.

"It was astonishingly provocative and below the belt because it was essentially trying to say I'd lied without the King being able to deny what I'd said." "I also thought it was a rather poor imitation of the ‘recollections may vary’ quote, which was a much more elegant way of putting things, but in these circumstances entirely out of place," he added.

The remark referenced the palace's famous "recollections may vary" statement issued after Prince Harry and Meghan Markle's explosive 2021 interview with Oprah Winfrey .

In the excerpt, published Wednesday, Spencer described a phone call he said he had with Charles six days after Diana died in August 1997.

"Prince Charles continued his stream of anger, without me interrupting.

Then he stopped.

I assumed the pause signaled an effort to bring himself under control, but then he unleashed down the phone what I have always taken to be his pent-up contempt for Diana, and his horror that the world was so bowled over by her death," Spencer alleged.

"‘Rest assured,’ he hissed, ‘we’ll forget her soon enough!’" PRINCESS DIANA'S HONEYMOON LETTER REVEALS A YOUNG BRIDE 'PLAYING WITH GROWN-UPS' IN THE ROYAL FAMILY According to the excerpt, the king and the 9th Earl of Spencer disagreed over the decision to have Prince William and Harry, then 15 and 12, walk behind their mother's casket during the funeral procession.
