A royal expert claims that Prince Harry was "angry" during the state funeral for his grandmother Queen Elizabeth II.

Dickie Arbiter reflected on the sad state funeral last September 19 and remembered the Duke of Sussex's body language. He said that the former royal had displayed anger by attending the funeral of the previous king or queen with his family.

The former butler turned royal expert claimed, in an episode of True Royalty TV's "The Royal Beast" via Express, that if you look at the images of Prince Harry, everyone was displaying solemnity like everyone else. But he also conveyed anger with his body language.

The subject of his relationship with Prince William was then brought up, and royal editor Duncan Larcombe brought up their ongoing conflict.

Larcombe even thinks Prince Harry and Meghan Markle's behavior shows a resemblance to the Kardashians and the British royal family.

"Netflix is following them around, and they're selling off the entire royal brand to the highest bidder."

Prince Harry apparently had second thoughts about publishing his eagerly awaited biography soon before Queen Elizabeth II passed away. It's unclear what exactly Prince Harry was upset about.

The British royal family is reportedly worried about what the Duke of Sussex could reveal in his book, according to recent sources.

According to Richard Kay, "There is still that potential that Harry is having second thoughts about when he will publish this book at all, and that the entreaties of the Royal Family have not gone on deaf ears."

Another royal expert claims that the bombshell book is to blame for the strained atmosphere in Buckingham Palace and that the royal family is taking a "bolts and braces" approach in preparation for the publication.

According to Katie Nicholl, Prince Harry is unlikely to cancel the book at this point since doing so would require him to return half of the significant advance money he has already received from the publishers.

"They're not afraid to have a go at members of the Royal Family, the Oprah interview put the Royals at the center of a highly heated storm over those charges of racism," she remarked to the Duke and Duchess of Sussex.

Belts and braces are required, but she remarked, "I cannot think that the prince will hand back half of that money and cancel the book."

Last year, Prince Harry revealed his plans for the book, stating he would write it as the "guy I have become," rather than as a member of the royal family.
