“They hadn’t seen each other. It’s really going to take a while to heal.
“I think the distance between the brothers widened more and more.
“And that’s partly because of the things that are happening – and we discuss that in the book.”
Mr Scobie’s book Finding Freedom is a biography of Sussex cohabitation that details the couple’s separation from the royal family.
The royal expert said the relationship between Prince Harry and Prince William had broken down because the Sussexes had announced their intention to step down as members of the royal family.
Mr Scobie said: ‘I think what really went wrong for Harry, Meghan and the Cambridges was this decision to go public with the roadmap for their new working model.

A source said: “It is completely wrong to think that William and Harry are communicating like before.
“The fallout is serious and difficult. Kate and Meghan do not communicate personally at all. “
Mr Scobie accused Kate Middleton of participating in the destruction of the relationship.
He said: “I don’t think there were really many attempts to make them stay.
“If I’m honest, and it’s emphasized throughout the book, Meghan and Kate’s relationship has really never progressed this far.
“Meghan felt that Kate hadn’t gone to much effort to look after her during some of the darker times, especially during her pregnancy. “
Mr Scobie also said the royal family ‘will stop at nothing to make Meghan’s life difficult’.
He said Prince Harry phoned the Queen ahead of her wedding to complain about her key assistant Angela Kelly over the helmet the Duchess of Sussex was going to wear.
The royal expert said: “Harry had to intervene. He called his grandmother and said, “I don’t know what’s going on. This woman must do this work for my future wife.
“Harry felt that there were those within the institution who would stop at nothing to make Meghan’s life difficult.
“Meghan was only able to try the tiara a few days before the wedding. “
