King 'hissed' brutal five words at Earl Spencer as Diana's brother claims he is being 'gaslit'

King 'hissed' brutal five words at Earl Spencer as Diana's brother claims he is being 'gaslit' Diana's brother claims that the King hissed the harsh "We’ll forget her soon enough" statement to him in a heated phone call after his sister's tragic death Earl Spencer has doubled down on his bombshell claim that King Charles of hissed "we’ll forget her soon enough" to him after Diana's death. Last week Diana's brother claimed in his upcoming book that Charles told him the insensitive statement on a phone call after his sister's death. The release of the snippet from the book started what has been branded a 'war' between the pair, receiving an unusual response from the palace. Charles Spencer has now reiterated the accusation, declaring to ABC News that the King "didn’t say it, he hissed it." The author of Swan Song: Diana, My Sister told the news outlet: "I’ll never forget the five words ‘We’ll forget her soon enough’ — and he didn’t say it, he hissed it." Last week Buckingham Palace hit back at the claim, stating: "While we do not comment on books as a matter of principle, His Majesty is mindful that the pain of fraternal grief can cloud reason, affect judgment and colour memory in ways others do not recognise, even many years after such a loss." Diana's brother said Charles is 'gaslighting' him with this response. Spencer told ABC: “It’s not everyday you’re gaslit by a King. "I was really upset by that because I thought it was not only condescending but not straight. What I said was straight and true and what did they come back with? That." The earl added: "I didn’t hold back but, and this is not a threat, I could have gone an awful lot further. “So, everything I say in the book is absolutely essential to the narrative and the understanding of the subject. “People have asked me if I’m bitter, angry or not, I’m really not, I’m not. "It’s not tittle-tattle. "I’m not trying to damage the monarchy or whatever I’ve been accused of doing. "I wanted to do this properly once and for all for Diana and remind those who knew her when she was alive, why they connected with her." The Mirror have contacted Buckingham Palace for comment.
