Prince Harry's animosity toward his family was "unprecedented," according to a royal expert.

Daily Mail's Royal Editor Rebecca English and the outlet's Diary Editor Richard Eden recently joined You Magazine Editor Jo Elvin for the latest episode of Daily Mail Royals' "The Palace Confidential." English is part of the royal rota and was among the members of the press who joined King Charles in his recent visit to the United Arab Emirates for the 28th United Nations Climate Change Conference (COP28) in November.  

In the special episode, they talked about the royal family's ups and downs this year. During the chat, Elvin asked if it wasn't just Prince Harry's book "Spare" that caused so many problems, but his series of interviews too.

"Yes, where he really drove home this unprecedented level of animosity towards his own family," English replied. "The book was bad enough, but he didn't hold back in those interviews either. I mean, you know, he's very vitriol about the press, we're used to that, that comes with the territory. But I just think what, and I don't think he has done himself any favors here."

English claimed that the people were shocked by what they learned from Prince Harry. She emphasized how most, if not all, are part of big families, and it's normal to have some misunderstanding within the household because, at some point, family members would rub each other the wrong way. However, for her, one doesn't "go and shame" their family like how Prince Harry did.

"And I think that's what's left such a nasty taste in people's mouths. They understand that he hasn't had the perfect childhood, but it's left people feeling really uncomfortable at the level of disloyalty he has shown to his family and the way he seemed to want to introduce them in public," English continued. 

"I don't think he's done himself any favors with that."

Meanwhile, Prince Harry's friend James Haskell, a former England rugby star who attended his wedding to Meghan Markle in 2018, defended him from those who questioned his move in doing those interviews. He supported Prince Harry's decision to speak his truth.

"When someone feels like they and their partner have been oppressed, lied about, contradicted and put into a corner, I think it's very important [to speak out]," Haskell said, per Daily Mail.

However, Haskell also admitted at Bath Forum in Somerset for the "World Cup Afterparty: The Good, The Bad and The Ugly" -- a live version of his popular rugby podcast with Mike Tindall -- that Prince Harry was more fun before he met his wife. He met Prince Harry for the first time at Tindall's wedding to Princess Anne's daughter, Zara, years before he started dating the "Suits" actress.
