He “stubbornly fought” to win his mum’s approval to marry Camilla Parker-Bowles, according to Tom Bower’s biography The Rebel Prince: The Power, Passion and Defiance of Prince Charles.
He organised Camilla’s extravagant 50th birthday party in July 1997 to change the public’s perception of her, the book claims.
Charles was determined to “transform her from adulteress into a suitable wife for the heir to the throne – and future queen”.
But Diana’s tragic death in a car crash just a month later “destroyed Charles’ plan”.
He reportedly told aides: “They’re all going to blame me, aren’t they? The world’s going to go completely mad.”
Her Majesty remained frosty towards Camilla during the Queen Mother’s funeral in 2002 and at her wedding to Charles in 2005.
Bower writes: “Few noticed that the Queen had not once mentioned Camilla by name. Nor did she speak to her during the party.
“‘I can’t believe it,’ the new bride repeated to her friends in the room. ‘I can’t believe it.'”
Daily Star Online has approached Clarence House for comment.
“They’re all going to blame me, aren’t they?”
We previously revealed that the Duchess of Cornwall is set to have a knockout new crown made for her when she becomes Queen.
A diamond-studded crown will be placed on the head of “Queen Camilla” when Prince Charles becomes King.
It will be the culmination of Charles’ attempts to give his wife the top title when the current Queen dies.
He hopes to make Camilla a “Queen Consort” – the title usually given to the wife of a reigning Monarch.
