The royal tradition Prince George is set to break when he finishes primary school.

It was only a few months ago we saw Prince George off to his first day of primary school, hand-in-hand with father, Prince William, in a ridiculously cute matching navy ensemble. Bless.

How time flies, because now there’s already talk of where the four-year-old will be going to senior school. Which, as anyone who has kids will know, isn’t unusual in the slightest as these kinds of decisions are often sorted out well before said child can even write their own name.

You’d think being the heir to the British monarchy would take the guess work out of such decisions, right? You’d just send your son the same school your Dad went to, and his Dad, and his Dad, and his Dad, yeah? Not if Kate and Wills have anything to do with it.

Being the rebels they are, the Duke and Duchess of Cambridge reportedly have other ideas for where their son will be going to senior school, that don’t include sticking with royal tradition.

As an “unofficial rule” (which you know is 100 per cent official), senior members of the royal family have attended same-sex boarding schools. For Prince George this would mean Eton College independent boarding school for boys where his father, uncle Prince Harry, and pretty much every character Colin Firth has ever played went before him.

However, a 'source' told the Sunday Times this likely won't be the case.

"The word on the street is that his parents want co-education and boarding when he leaves prep school," the source said.

Well, if that's the "word on the street", then it must be true, right?

As to where the Prince would attend, The Sunday Times also noted Brighton College could be a strong contender, as it's been a popular choice of senior education for kids from George's school, Thomas’s Battersea.

While there are definitely pros and cons to both same-sex and co-ed schools, we're quietly hoping Kate and Wills decide to break from tradition, if only to see the look on the Queen's face.
