Prince Harry and Prince William’s alleged rift reportedly has links to their late mom Princess Diana.

The Sun’s royal correspondent Emily Andrews spoke to a palace courtier about the royal siblings’ falling out and was told that Prince Harry went mental after his older brother tried to wreck his relationship with Meghan Markle.

“As one royal courtier told me: ‘It’s my opinion that Harry feels he couldn’t protect his mother, so he’s going all out to protect his wife. This is his way of atoning. He will book absolutely no criticism of Meghan – and he is so sensitive he often sees criticism or negativity where there isn’t any,’” she said.

This is not the first time that Prince William and Prince Harry locked horns. The future King was furious at his younger brother when he learned that Prince Harry stripped off his clothes in a Las Vegas hotel room years ago. But at the end of the day, the siblings have always turned to each other for support.

However, Prince Harry was angered after Prince William tried to convince him not to marry Markle.

“William told his brother they knew nothing about her background, her intentions, what she was really like. He just wanted to stress that becoming part of the royal family is a massive undertaking and the pressure and scrutiny is unrelenting. Was Meghan the right one?” a palace source said.

Unfortunately, Prince William’s remarks did not sit well with Prince Harry. The Duke of Sussex went mental, and he accused his brother of trying to end his relationship even before it began.

“The brothers’ relationship has not really recovered,” the source said.

One of Prince William’s friends also told the Daily Mail, “The problem is that the Cambridges felt things had moved very quickly between Harry and Meghan. Wills particularly was worried and felt close enough to Harry to voice his thoughts.”

Multiple sources claimed that Markle and Kate Middleton are not on good terms. The Duchess of Sussex is rumored to have made the Duchess of Cambridge cry. However, Kensington Palace denied the claims.
