A Spanish-language version of Prince Harry's memoir "Spare" was being sold in bookstores in Spain on Thursday ahead of its official launch date.
The book reveals details about Harry's relationship with his family that have never previously been published. Perhaps Harry's most explosive claim is that his brother Prince William pushed him to the floor in an argument over Harry's wife Meghan.
Following are some of the key details outlined in the book:
Camilla
Harry says that he and Prince William had asked their father not to marry Camilla Parker-Bowles, who is now Britain's queen consort. Nonetheless, he writes that both he and William ended up wishing their father a happy marriage and had some sympathy for their relationship.
"Despite the fact that Willy and I asked him not to do it, my father went ahead. Despite the bitterness and sadness we felt in closing another loop in the history of our mother, we understood this was irrelevant."
Dressing as a Nazi
Harry says he was encouraged by Prince William and Princess Catherine to go dressed as a Nazi to a fancy dress party in 2005, in what he has described elsewhere as "one of the biggest mistakes of my life". Harry says he visited a costume shop and found several options for the party. He called William and Kate for advice and said they immediately suggested the Nazi uniform.
Major Hewitt rumours
Harry refers to media rumours that he was the result of an affair between Major James Hewitt and his mother Princess Diana and suggestions that his father King Charles often joked about not knowing who Harry's real father was. Harry says the idea is absurd, given that his mother did not meet Hewitt until long after he was born.
Fight over wedding venues
Harry claims the royal household dragged its feet over the date and venue for his wedding with Meghan. He said that when he consulted William about the possibility of marrying in Westminster Abbey or St. Paul's Cathedral, William said he could not marry in either of those because they had been venues for the weddings of Charles and Diana and William and Kate respectively. Instead, William suggested Tetbury, a village chapel near Highgrove House in the Cotswolds.
Drugs
Harry says that when he was 17 he was offered a line of cocaine at someone's house and consumed the drug on several other occasions, although he insists media reports suggesting he was a drug addict were false and that he did not enjoy it.
"It wasn't much fun and it did not make me feel especially happy as it seemed to do to everyone else, but it did make me feel different, and that was my main objective. I was a 17-year-old boy ready to try anything that altered the pre-established order, he writes.
Harry also recounts how, as a student at the exclusive private school Eton, he used to smoke cannabis in a bathroom at his house while the Thames Valley police served as his bodyguards, patrolling the exterior of the building.
Message from his mother
Harry describes meeting a woman with "powers" who said she could feel Princess Diana's spirit. He says the woman was recommended by friends and that, while he had his doubts about her, as soon as he sat down with her "I felt an energy around her".
"Your mother says that you are living the life that she couldn't live, the life she wanted for you," Harry quotes the woman as telling him.
But Harry says he was still sceptical and wanted more proof. The woman told him Diana mentioned a Christmas decoration. Harry said it must have been the one his son Archie had tried to fix.
Frostbite in his crown jewels
Harry describes how during a trip to the North Pole he suffered from early stages of what appears to be frostbite, including to his penis. He recounts telling his father about his injuries at a dinner on the eve of William's wedding.
"My father showed interest and sympathized with me when I mentioned that my ears and cheeks had burned due to the cold. I struggled to contain myself to not talk too much and tell him that my penis had also been affected..."
