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. Harry says he visited a costume shop and found several options for the party. He called William and Kate for advice and he said they immediately suggested the Nazi unfiform.

HARRY BREAKS SILENCE ON MAJOR JAMES 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 his 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.
