Earl Spencer’s book claims Charles acted 'elated' after Diana’s death

King Charles allegedly acted like a “lottery winner” in the hours after Princess Diana’s death, her brother Earl Spencer has claimed in his bombshell new memoir.

In the latest serialisation of the damning book, the then-Prince of Wales is accused of appearing “giddily elated” on the phone, shortly after his former wife had been killed in a car crash in Paris.

The allegations sparked a punchy response from Buckingham Palace. "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,” it said.

In an extract published in the Daily Mail on Thursday, the royal family are accused of showing “arrogance and entitlement” in the organisation of Diana’s funeral, and that her family’s request to have Mozart’s Requiem played was rejected, despite those being her wishes.

Earl Spencer said that the excuse that no requiem song could be played at a Church of England service was the “first of several untruths that the authorities would push my way”.

Charles, who was prince at the time the allegations refer to, allegedly made the remarks that Diana would be forgotten during an argument over the decision to have princes William and Harry, who were aged 15 and 12 at the time, walk in their mother’s funeral procession.

After Earl Spencer opposed this, Charles allegedly phoned him and remarked in a “stream of anger” that his ex-wife would soon be forgotten.

In his memoir titled Swan Song: Diana, My Sister, Earl Spencer claims that he argued Diana would not have wanted her sons to join the procession.

“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. ‘Rest assured,’ he hissed, ‘we’ll forget her soon enough!’” the memoir claims.
