Why Prince William will avoid meeting with Prince Harry on next UK trip

Prince Harry and his wife, Meghan Markle, are heading back to the UK in September. But according to royal experts, Prince William is unlikely to entertain the idea of a reunion with his brother until he has read his memoir, reports the Daily Mail.

Due to be released in October, Prince Harry's book is reportedly a "first-hand account of his life". Written by Pulitzer prize-winning ghostwriter JR Moehringer, it claims to be "accurate and wholly truthful".

And its pending release is said to be the reason Harry's brother will not see him when he goes home this September.

Royal biographer Angela Levin claims William and his wife Kate, while also "very busy" at the moment, will be holding off healing the alleged division that has existed between the royal brothers and their wives since before Harry and Meghan stepped down as senior royals in 2020.

"[The Duke and Duchess of Cambridge] are extremely busy at the moment," the royal author told the Daily Mail. "They're moving home, they need to settle their children into new schools. They're very busy taking on so many more engagements for the Queen."

Levin went on to say making amends would be "very difficult and certainly not before [Harry's] memoir comes out because we don't know what he's going to say.

"[Harry's] been very unkind and cruel so far. We have to wait to see what he does - maybe they won't want to see them until all that's out in the open and they know what he says."

Another royal expert, Richard Fitzwilliams, has seconded Levin's claims. He told Femail the Cambridge-Sussex rift is "very deep" and doubts a reunion when the Sussexes return to the UK "probably won't" be seen.

"I suspect that the rift is very deep, the reports are that they probably won't," he said.

While the Sussexes, who have made a new home in Montecito, California, have returned to the UK twice this year, it is claimed they did not meet with the Cambridges on either visit.

According to the Daily Mail, William and Harry have not spoken to each other "face-to-face" since the unveiling of their mother Princess Diana's statue in July last year.

The Sussexes will travel to the UK for the One Young World Summit, to be held in Manchester. It is understood Meghan will give the keynote address at the opening ceremony.

The next day the pair will head to Germany to commemorate a year until the Invictus Games in Dusseldorf.

From here they return to the UK for the WellChild Awards in London, where Prince Harry will deliver a speech.
