Prince Harry has been urged to "go and visit" his sister-in-law Princess Kate whilst he is in the UK.
Former editor of The Sun Kelvin MacKenzie has waded in on the "pathetic warfare" between the duke and the rest of the Royal Family.
Speaking to GB News, MacKenzie said: "This is a long, drawn out kind of war. All families have these issues.
"The thing I would most like to see is actually Harry, to go and see Kate. It would be good to see whether something could be done there.

"It is incumbent on Harry to make the first move. Right? He's the one who is not ill. It's pathetic to see this kind of warfare played out in public."
LATEST DEVELOPMENTS
Sources have told People Magazine that Harry's attempts to communicate with King Charles and Prince William have gone unanswered.
Harry's solo appearances in New York and London are seemingly part of a new strategy where he performs engagements without his wife Meghan Markle.
Speaking about the pair's recent professional separation and whether it could indicate "trouble in paradise", MacKenzie told GB News: "All I would say is she [Meghan] clearly doesn't want to be here.

"Actually, funnily enough, the people in this country don't want her here. I think they'd probably like to see Harry's children."
Harry and Meghan left the UK in January 2020 and after a short stint in Canada, they moved to the US.
The have since released several damning statements about the Royal Family in the form of interviews and Harry's memoir Spare.

When Kate was first diagnosed with cancer, only a select few members of the Royal Family were told, and Harry was not one of them.
The Sussexes did release a statement that read: "We wish health and healing for Kate and the family, and hope they are able to do so privately and in peace."
Before the dramatic royal exit, Harry had a close bond with his brother and Kate, who he previously described as "the sister I've never had and always wanted".
