Prince Harry has been asked to step in and make amends with his brother Prince William instead of giving interviews to US media.
Royal expert Russell Myers wants estranged siblings William and Harry to 'sit down' and plan the future of the monarchy together.
Speaking on Australian TV, Mr Myers said: "We saw the Platinum Jubilee celebrations, unfortunately, they didn't go out at all."
Mr Myers recalled how during the Queen's Jubilee Harry 'stretched his neck' in hopes of catching a glimpse of the older brother, noting that the younger one still needed the future king's approval.
Mr Myers said: "He didn't spend any of those four days at all, but I think Prince Harry should stop giving interviews to American television networks before the two brothers sit down and get back to their best performance." Go and I guess it's not going to happen long ago."
According to Mr Myers, Harry showed a sign that he was "desperate for approval from his brother".
When host Karl Stefanovic commented: "I didn't realize the fact that it was probably coming from William's shutout as opposed to Harry.
“I think we all assumed, given the bad press around Meghan and Harry, that it was always like subjugating people, but really, Harry is looking for approval from his brother, but His brother is closing the door."
Harry "still yearns to belong to his family," predicted Mr. Myers.
He added: "While he's still giving interviews, he puts them off from time to time, unfortunately it's a very, very long way for him at the moment.
"I think there should be a little more space between these boys before they can get back together."
