In the heartwarming picture, the Good Morning Britain weather star posted a photo of a young Charles sitting with his sons as children.
He captioned the post: “I just want to hear that The King, Princes William and Harry were all in a room united in the love they have for their father. That kind of medicine the doctor can’t prescribe.”
Royal fans agreed as one replied: “I said straight away, I hope that Harry & William can sort things for there fathers sake! Glad he’s been told.”
Another tweeted: “Glad prince harry is on his way to see his father. Family is family in these circumstances.”
A third commented: “Indeed!” while another added: “Me too.”
The Duke of Sussex has spoken with the King about his cancer diagnosis and will travel to the UK to see him soon.
“The duke did speak with his father about his diagnosis. He will be traveling to UK to see His Majesty in the coming days,” the source close to Harry told the Press Association.
According to reports from the Telegraph, Harry is expected to fly to the UK tonight, but his wife Meghan Markle and their two children, Prince Archie and Princess Lilibet will not travel alongside him.
Prior to the King’s cancer diagnosis, his relationship with youngest son Harry had been strained, reportedly due to claims the Duke of Sussex made about his father and the Royal Family in his book, Spare.
Harry did attend Charles’s Coronation last year, but left the UK shortly after the ceremony concluded.
It was then claimed the father and son duo shared a “warm” phone call when Charles marked his 75th birthday in November.
