“To have three different schools in three different parts of the country, I think would be very difficult. I feel very sure that this is what Kate and William will want to do.”

She also suggested that William and Kate would likely want George to have a less rigid school experience. “He’s had a lot of formality in his young life, and I think they would probably want him to be certainly co-ed and just somewhere where he’s free.”

Eton College remains a possible choice, given its proximity to Adelaide Cottage, the family’s current residence.

Seward also speculated that William and Kate might consider boarding school, emphasizing the flexibility of modern institutions. “They can come home whenever they want to. They can come home at weekends if they’re not too busy playing sports,” she explained.

“Boarding schools nowadays aren’t like one imagines the boarding schools of old. I think it’s very much more flexible than the idea of these very strict sort of Tom Brown School Days.”

While Prince George’s next school remains undecided, Prince Louis, six, and Princess Charlotte, nine, still have a few more years at Lambrook before any changes.
