Following news of the King’s cancer diagnosis on February 5, Harry publicly revealed that he was to travel to meet his father – and did so just one day later.

Harry, however, has not met William during any of his recent visits, with one expert recently saying that the Duke “doesn’t really exist” to William.

Speaking to Times Radio last month, royal expert Jennie Bond dismissed speculation about a possible reunion between the pair as she claimed William “has no room” right now to focus on reuniting with Harry.

She added that this is mainly down to the his wife’s cancer diagnosis and her recovery – as well as caring for their three children, Prince George, 10, Princess Charlotte, 9, and Prince Louis, 6.

Ms Bond said: “I think William has enough pressure on his heart and his head with his wife undergoing cancer treatment and his father, and the big job, and his kids, I don’t think he’s got room in his soul to worry about his estranged brother.

“For all intents and purposes, William has disowned Harry.”

Harry had been expected to reunite with his father during his brief return to the UK last month, however he wasn’t able to meet his father due to Charles’ “full programme”.

It remains unknown when Harry last met with William.

Prince Harry now resides in the US with his wife Meghan Markle and their two children, Prince Archie, 5, and Princess Lilibet, 3.
