King Charles has welcomed the idea of Prince Harry and Meghan Markle moving back to Britain following his cancer diagnosis to spend more time with his grandchildren, Prince Archie and Princess Lilibet. Despite ongoing grievances, both sides are making efforts to resolve their years-long rift, though a slew of recent setbacks has kept the monarch preoccupied with crisis meetings instead.

"Here he was expecting that they'd be getting straight into making up for lost time, and it's been quite the opposite," a source said. "Harry keeps promising him that the visit will happen very soon, but so far there's been no date set, and Charles is feeling very let down," the insider added.

Logistical challenges also remain because Archie and Lilibet must be accompanied by at least one of their parents, making scheduling difficult. "It's not as easy as just popping over for a visit with the kids," the source said.
