Following Prince Harry's move to the US in 2020, his fractured relationships with other members of the royal family were thoroughly scrutinised and became the subject of much 'feud' speculation - particularly when it came to his brother, Prince William, and father, the now-King Charles.
Both the King and the Prince of Wales have remained tight-lipped about the nature of their relationships with the Sussexes, but Harry has gone on to share his own feelings and experiences in the Netflix docu-series Harry & Meghan, as well as in his memoir, Spare.
His attendance at Charles' coronation earlier this year signified to some that there was a possibility that Harry could reconcile with his family, but when he returned to the UK weeks later the King was unable to see him.
Now, royal expert Robert Jobson - also the author of Our King Charles III: The Man and the Monarch Revealed - has told the Daily Express that Kate is the only member of the family 'helping the situation' and that despite taking on the difficult role of mediator she is 'doing a brilliant job'.
In fact, Jobson claims that Kate is actively trying to help the estranged brothers by getting William and Harry to talk again.
He said: "I'm not sure how much dialogue there is with William and Harry, at the moment, I think the only person that is helping the situation is Catherine, who is doing a brilliant job.
"First of all when the King wants to see his grandchildren, for example, it's important to say that a lot of it has been through Catherine. But William and Harry, it's a difficult one. I think as brothers they are more likely to get on the phone and have a conversation."
Although there are efforts to bring them closer together, the royal author also notes that the trust between Harry and William has taken a huge hit following the release of the Duke of Sussex' memoir.
He said: "It's quite possible that one of them might pick up the phone to have a rant, but who's gonna pick up the phone on the other end? Because that's not gonna achieve anything.
"There's also a lot of lack of trust at the moment between all the members of the family and Harry about where this information is going, because a lot of stuff has appeared in print by him."
