King Charles is set to face a Prince Harry "problem" next week as the Duke returns to the UK, former Royal Correspondent Michael Cole has warned.
The Prince will set foot in Britain for the first time since his flying visit to his father following his cancer diagnosis.
Harry will attend a commemorative service for the Invictus Games to mark ten years since it began.
Speaking to GBN America, Michael Cole questioned if the Prince would reconcile with his father during his visit before he flies to Nigeria with Meghan Markle.

Cole told GBNA that "no senior members of the Royal Family" are expected to attend the service, despite the King receiving "good news" about his cancer treatment.
He praised the monarch's return to duties, adding: "It's good news for the King. The doctors are happy with the way the treatment is going, and he's returning to more public-facing duties, which I know is what he wants to do."
Noting Prince Harry's return on May 8, Cole claimed he may be a "problem" for King Charles.
He told host Nana Akua: "Of course, there is the Harry problem. He's coming next week for the 10th-anniversary service of Thanksgiving at Saint Paul's Cathedral.

"I think it will be a key moment because we will see whether the King will receive his son."
LATEST DEVELOPMENTS:
Remaining optimistic about a reunion between King Charles and his youngest son, Cole admitted: "I think he will see him. I think there's a good possibility that he will be in town. The King has other duties.
"And he has always made it clear that his door remains open to his youngest son."
Cole added: "The prodigal is always welcome at home. Of course, he has to be contrite, and he has to ask for forgiveness beforehand, but the King will do that."
However, Cole shed doubt on any reconciliation between Prince Harry and his brother, Prince William.

He told GBNA: "What, of course, will not happen, is that there will be any reconciliation with his older brother, William.
"Harry and his wife Meghan have not taken any pains to withdraw the unkind, cruel and entirely bogus allegations that they've made, particularly against the Princess of Wales now undergoing her own treatment for cancer.
"You would have thought that they might have done that, but they haven't done it."
