Prince Harry has said he saw a “red mist” in Prince William during an argument between them, claiming his brother “wanted me to hit him back, but I chose not to”.

In a new trailer for ITV’s forthcoming interview with the Duke of Sussex, he recounts an altercation with his brother.

“What was different here was the level of frustration, and I talk about the red mist that I had for so many years, and I saw this red mist in him,” he says.

“He wanted me to hit him back, but I chose not to.”

The duke describes the incident in his much-anticipated memoir, Spare.

It is due to be released next week but Sky News obtained a copy after it was accidentally put out for sale early in Spain.

In the book, Prince Harry makes several jaw-dropping allegations about the Royal Family, along with revelations about his own life, including his use of cocaine, how he was told about his mother’s car accident and the moment he lost his virginity.

In the clip, the duke is asked about the drug use he describes in the book.

Interviewer Tom Bradby says: “There’s a fair amount of drugs. Marijuana, magic mushrooms, cocaine. I mean, that’s going to surprise people.”

The duke says he believes it is “important to acknowledge”.

He also repeats his desire to reconcile with his brother and father, the King.

“I want reconciliation. But, first, there needs to be some accountability,” he says.

“The truth, supposedly, at the moment, has been there’s only one side of the story, right?

“But, there’s two sides to every story.”

In another section of the tell-all memoir, he describes being in Paris at the age of 23 and asking a driver to take him through the Pont de l’Alma tunnel at the same speed as the car carrying his mother, Princess Diana, when it crashed in August 1997.

“I told myself I was only doing it to close that chapter, but it was not true,” the duke writes on page 188.

Adding that the drive was a “terrible idea,” he went on to write that there was “no reason anyone should ever die inside the tunnel”.

“Deep down, what I was hoping to feel in that tunnel was what I had felt when JLP [a former palace press secretary] had given me the police reports; mistrust. Doubt. However, that was the night all doubts were dispelled. She’s dead, I thought. My God, she’s really gone forever.”

He goes on to explain that the next day, he called his brother, Prince William, to tell him what had happened, and the pair decided to drive through it together before heading to the rugby final.

It was after this that they spoke about their mother’s accident for the first time, Prince Harry claims, adding that they discussed issuing a statement and calling for the investigation into her death to be reopened.

‘Why had those paparazzi got off lightly?’

The inquest into Diana’s death heard that her car was travelling at between 60mph and 65mph – around twice the 31mph (50kph) limit for the road – when it struck the 13th pillar of the westbound carriageway in the underpass.

“The final report was an insult. A load of nonsense plagued with factual errors, where logic was conspicuous by its absence,” the prince wrote.

“Especially the summary conclusion, that our mother’s driver was drunk and, as a result, that was the only cause of the accident.

“Even if the man had been drinking, even if he had been drunk, he wouldn’t have had any problem driving through such a short tunnel. Unless paparazzi were following him and dazzled him. Why had those paparazzi got off lightly?”

Prince Harry added that both he and Prince William agreed that they would call for a number of questions to be answered but “those who decided dissuaded” them from taking any action.

Sky News has approached Buckingham Palace and Kensington Palace and both will not be commenting on the allegations.

‘I want a family, not an institution’

In an earlier teaser clip of his upcoming ITV interview, Prince Harry refuses to confirm whether he will attend his father’s coronation in May.

He is heard saying that he wants “a family, not an institution”.

Making more extraordinary claims, he said: “They feel as though it is better to keep us somehow as the villains.

“I would like to have my father back. I would like to have my brother back.”
