Prince George is set to be separated from a "frustrated" Prince William in an "awkward" royal move, a royal author has claimed.
Robert Jobson, who has written a new biography on the Princess of Wales, appeared on this week's episode of The Royal Record podcast where he discussed the second-in-line to the throne, Prince George.
Svar Nanan-Sen, GB News's Digital Royal Editor, asked Jobson about an age-old royal rule that states two heirs to the throne cannot travel together in case of a tragedy occurring.
He said: "William stopped flying with Charles when he was aged 12.

"Do you think we'll see something similar where Prince George takes a separate flight from William next year when he turns 12?"
Jobson responded: "I suspect that's going to be considered. The fact that the King has raised it before George was 12, I think, is important.
"When you've had a cancer diagnosis like the King has had and the treatment he's had, he's obviously thinking about his own mortality and the future of the monarchy.
"And that involves Prince George very much so, left, right and centre. So I think that it's quite important."

In February, Buckingham Palace announced that the monarch, 75, had been diagnosed with a form of cancer.
He has since modified his schedule to accommodate his cancer treatment, which he is receiving as an outpatient.
Jobson added that Princess Kate and Prince William could be "frustrated" with the royal rule that George, 11, would have to travel separately from his father and potentially his younger siblings.
He continued: "I can understand why there was frustration because if you're going to separately get one child to take a different route, it can be quite awkward if you're going on holidays and things like that.

"I'm not so sure that if you're going on a commercial flight or something like that, it would be so necessary.
"But helicopters do tend to be the focus. Mind you, we've had a few billionaires, haven't we, that have crashed in helicopters who must have thought with their wealth and experienced pilots and wonderful helicopters that they were indestructible, but they weren't.
"So I do think that it's just a question of making sure that the monarchy and the line of succession is safe."
