In a statement released last month, Kate revealed she was making good progress but was “not out of the woods yet” and had “good days and bad days” as she continued her treatment.

In time for his 40th birthday on September 15, Harry is said to be keen for their differences to be put to one side once and for all. But since his departure from the Firm, Harry and Meghan have been fiercely critical of the monarchy, from their televised interview with Oprah Winfrey to their Netflix series ‘Harry & Meghan’.

Royal critics have suggested a lot of effort needs to be shown for the two brothers, Harry and Prince William to make amends. Former BBC correspondent, Jennie Bond told Times Radio: “I think as far as William is concerned, Harry really doesn’t exist. William has enough pressure on his heart and his head, with his wife and her ongoing cancer treatment, and his father, his job and his kids that I don’t think he’s got any room in his soul to worry about his estranged brother… I think William has disowned Harry.”

Prince Harry last visited the UK for the 10th anniversary of the Invictus Games in May at St Paul’s Cathedral. However, he failed to see any immediate family members.

The last time the father and son duo were together was in February when Harry jetted off to London following King Charles’s cancer announcement, but he spent less than 25-hours in the UK’s capital before returning to America.

Shortly after, he flew to Vancouver, Canada to attend the ‘One Year to Go’ event ahead of the winter Invictus Games 2025.
