Prince Louis and Princess Charlotte could be ‘renting a flat in Shoreditch’ as royals may look at moving away from palaces in the future, an author has claimed.

Kate Williams, believes the family’s 30 residences could be further opened to the public to provide funds for the royal collection.

Williams says historically, Queens have been more favourable of palaces, while Kings have tended to see them as “stages for brilliance”.

Queen Elizabeth II was known to be fond of both Windsor Castle, in Berkshire, and Sandringham in Norfolk. But her absolute favourite was said to be the Balmoral Estate in Scotland.

Williams expects such grand buildings could be opened up to the public, with “minor royals” having to relocate as King Charles looks to run a slimmed-down monarchy.

Speaking to Hello!, she said: “On one hand, these palaces are great homes being conserved for future generations.

“On the other hand, they generate a lot of income for the royal collection and are great to visit.

“We understand that King Charles is aiming for a slimmed-down royal family, so it means [minor royals] may have to go and live in non-palaces. He doesn’t really live in Buckingham Palace at the moment, he’s renovating it and using it more as an office.

“And it will be interesting to see how Prince William might approach them if he still has children living with him. Maybe in the future we’ll see Princess Charlotte and Prince Louis getting a flat in Shoreditch together.”

Currently the King and Queen Camilla use Clarence House as a London residence with Windsor Castle remaining as the official country residence.

Meanwhile Kensington Palace is used as the official residence for Prince William and Princess Kate along with their children George, 10, Charlotte, nine, and Louis, six.

The Duke and Duchess of Gloucester, The Duke and Duchess of Kent and Prince and Princess Michael of Kent are also based in the palace's royal apartments.

A number of royal residences - including Kensington Palace and Windsor Castle - allow public visitors in areas. While Buckingham Palace opens in part to the public for palace tours.
