'Everyone is absolutely sick of Harry being revoltingly rude about the King and William'

Harry and Meghan likely had a huge argument about whether to attend the King's coronation, according to royal biographer Angela Levin.

Speaking to TalkTV's Julia Hartley Brewer, she said: "I don't think Meghan believes in supporting anyone in her family; it's all about herself.

"I think Harry was the one who was very worried about whether he should or shouldn't go. In the end I suspect they had a huge argument after decided he would go and she would stay behind."

Buckingham Palace announced last night that Prince Harry will attend his father's coronation alone on 6 May, as his wife has chosen to stay in California with their two children.

This comes after tensions between the pair and Harry's family have reached breaking point following the publication of his memoir Spare.

Angela added that Meghan's decision not to attend may not have been good news for the King.

"I think everyone is absolutely sick and tired of hearing Harry being revoltingly rude about his father and his brother," she said.

"So, it's not great news, but it is news that perhaps King Charles would be more pleased about.

Angela denied rumours that Kate, Princess of Wales, insisted she would not share the Buckingham Palace balcony with Harry and Meghan.

"No, she wouldn't. She's a very polite young woman. Of course she has an opinion but she wouldn't try to overrule the King. She knows her place."
