Prince Harry and Prince William's bitter Royal Family feud 'will continue for years'

She added that reconciliation is not a short-term goal for either of the royals.

Mansey said: "I've spoken to people very close to the family, who when Harry said he was coming, said, 'Well there is not going to be anything beyond that service at the Abbey as far as those members of the family, were concerned.'

"They don't want to hang out with him. They don't want to chat to him.

"And why would you when he's revealed private details of conversations in his book and who knows when the next TV show or the next interview is coming from the Duke of Sussex.

"So obviously people are cautious."

She continued: "I think William and Harry, that's going to be years before that riff can die down.

"I think there is hope. People I'm speaking to in the Palace who know the Princes well, they've known them for years and years, seen them grow up and seen them fall apart and get back together, do have hope that they will be reconciled at some stage but that is not short term.

"That's not a short-term goal for anything and also the King is going to be very busy."

It comes as Prince William and Kate have reportedly not spoken to Prince Harry since Queen Elizabeth II's funeral in September 2022.

King Charles is understood to be the only senior member of the Royal Family who is speaking to the Duke and Duchess of Sussex.

Earlier this month, a source claimed Prince William was left "baffled" by his brother's decision to delay announcing his attendance at King Charles's Coronation.

The Prince of Wales felt his brother was "deliberately stringing out" his announcement.

Prince Harry finally announced he will attend the historic ceremony on April 12 2023.

Meghan Markle will stay in California with their children Prince Archie and Princess Lilibet.
