The 'massive break in royal tradition' when Prince George will be King

Prince George will bring a "massive break in royal tradition" when he becomes King, according to a royal commentator.

Simon Vigar said he understands that the young prince, 10, will continue to slim down the monarchy when he gets the top job, following in his grandfather King Charles's footsteps.

He also said that George would be likely to make the monarchy "less formal" and potentially avoid serving in the military, but Mr Vigar added he could miss out on an "important sense of discipline" if he did not go into the forces.

Mr Vigar said: "It is a slimmed-down Royal Family already.

"It is less formal, it's not quite as starchy as it used to be, and I think George will continue that.

"You know he's the first future king to have a 'commoner' as his mum, that in itself is a massive break from tradition."

Richard Kay, another royal commentator also weighed in on how George would rule, saying the future British monarchy will be "much more like the monarchies on mainland Europe".

Kay said in the documentary Prince George: A King for the Future: "Charles is trying to manage the monarchy from a monarchy that was really founded on empire into one where we're now just a small island and country.

"And we have to adjust our expectations and by the time George becomes King, the monarchy will be very different."

Last year, it was reported that George would not be expected to serve in the military before becoming King, breaking centuries of tradition.

It would be a significant departure for the Royal Family as the monarch is commander-in-chief of Britain's forces.

George's father, uncle, grandfather, great-grandmother and great-grandfather all served in the military, sticking to a centuries-old precedent.
