It was thought that the feuding royals would put the worst of their differences behind them after their grandmother died. It isn't so fast.

According to the Guardian, which obtained a prerelease copy of Harry's forthcoming memoir in which the incident is detailed, Harry has alleged that William once physically attacked him over the former's marriage to the latter's daughter. The couple's acrimonious split from Buckingham Palace has been the subject of a number of allegations.

According to a report by The Guardian, William knocked Harry to the floor during a heated conversation at Harry's home in London.

The book, believed to be a juicy tell-all of Harry andMeghan's dealings with the House of Windsor, has been kept under wraps by publisher Penguin Random House.

Since their public stepback from royal duties in 2020, the Duke and Duchess have spoken out on their struggles within the Firm, including dealing with mental health troubles, British media venom, and alleged racism within the monarchy's circles. The Palace has not commented on the couple's claims.

There is a new allegation Harry has brought to light.

How does Harry describe what happened in London in 2019?

According to Harry, he and his brother had an argument in the grounds of the palace. The British press has been critical of their marriage and William came over and talked about it.

According to Harry, William called his brother "rude," "abrasive" and "difficult" and that he was parroting false media narratives. Harry accused his brother of being an heir.

According to the account, William told Harry that he was only trying to help. I need help. Is that what you're calling it? I'm helping me.

Harry went to the kitchen to get William a drink of water. William went down the water and came at Harry.

It all happened in a blink of an eye. In his memoir, Harry wrote that he was so fast. He ripped my necklace and knocked me to the floor. The dog's bowl cracked under my back and cut into me. I lay there for a while and told him to leave.

William urged Harry to hit back, but he didn't. According to the telling, William apologized and left the cottage, but not before saying that Harry did not need to tell Meg about the altercation.

According to reports, Harry disclosed the fight to her after he discovered the injuries on his back.

What to know about Harry’s memoir, Spare

The title refers to the idea of a firstborn royal child being in line to inherit the throne, while subsequent children are just backups. In the U.K., William has always been a spare, while Harry has always been the heir.

According to the Guardian, the unifying theme of his book is his resentment of this second-tier status and his relationship with his parents and brother.

The CEO of Penguin Random House called Harry's memoir "a remarkably moving personal journey from trauma to healing."

The publisher's website says that the proceeds from Spare's sales will go to British charities.

How is Harry promoting the book? What else has he said?

In the lead-up to the book's release, the duke did two TV interviews, one with iTV and the other with 60 Minutes on CBS. Both of the interviews are going to be broadcasted on Sunday.

Harry told Tom Bradby that he wanted to get his father back. I want to have my brother back. He said that they showed no willingness to reconcile. It's better to keep us as villains.

In a clip from his upcoming 60 Minutes interview with Anderson Cooper, Harry says he and his wife would have liked to live a private life since they moved to Canada and then California. When silence is betrayal, there is a point.

The December release of a six-part documentary series by and about Harry andMeghan on the internet preceded the interviews. The show shows the rift between Harry and his family. In one episode, Harry says, "So that he's now on the institution's side, and part of that" That is his inheritance.

Harry may have been destined to be the spare, but he has proved to be anything but.
