Prince Harry has said in his new book that he asked his father not to marry Camilla.

The duke also talks about the moment he was told his mother had a car accident, amongst a number of other revelations.

Speaking about the time his father was introducing him to Camilla, the prince writes: “That’s why when the question came, Willy and I promised our father that we would welcome Camilla to the family. The only thing we asked for in return was that he didn’t marry her. ‘You don’t need to get married again’ we asked him.”

Harry admits he took cocaine – live updates

The book Spare was mistakenly put on shelves in Spain, five days ahead of the official release date – but Sky News has obtained a copy.

Harry also detailed in the book the moment that he found out that his mother, Princess Diana, had been in a car accident.

He said he was woken up by his father who “sat on the edge of the bed and put his hand on my knee”.

He says Charles said: “My dear son, mum has had a car accident.

“There have been complications. Mum has been seriously injured and has been taken to hospital, my dear son.”

The book added: “He would always call me ‘dear son’, but he was repeating it a lot.

“He spoke quietly. It gave me the impression he was in shock.”

Diana died in 1997 following a car crash in Paris.

In the book, he also admitted that he took cocaine, spoke about how he lost his virginity and claimed his brother physically attacked him during a row over his marriage to Meghan Markle.

Speaking about using cocaine, Prince Harry said “it wasn’t very fun, and it didn’t make me feel especially happy”.

Harry described losing his virginity as “a humiliating episode with an older lady”.

He said it was “with an older lady, who loved horses very much and treated me like a young stallion”.

The excerpt read: “‘I mounted her quickly, after which she spanked my ass and held me back… one of my mistakes was letting it happen in a field, just behind a busy pub. No doubt someone had seen us’.”
