Prince Harry Said Kate Middleton 'Almost A Prisoner In Kensington Palace,' Royal Expert Claims

Kate Middleton and her family's rumored move from London to Berkshire, England, would give them much more freedom, according to a royal expert.

Royal biographer and editor-in-chief of Majesty magazine Ingrid Seward weighed in on reports that Prince William and the Duchess of Cambridge plan to leave their home at Kensington Palace and relocate to a new residence in Windsor, where Queen Elizabeth II lives.

Seward, who has written several books on the royals including "Prince Philip Revealed: A Man of His Century," said on True Royalty TV's "The Royal Beat" that Middleton is unable to do things like walk in the park while living in the London palace and moving to Berkshire would be great for the whole Cambridge family.

"I think what William and Catherine will have for their children is the freedom they didn't have at Kensington Palace," she was quoted as saying by the Mirror. "I remember Harry saying to a friend of mine that Catherine was almost a prisoner at Kensington Palace, and I thought don't be ridiculous, it’s the most gorgeous place to live in London!"

She added, "Then I thought, in a way they are prisoners, they have a beautiful house and garden but beyond that garden are hundreds of people every day and massive security."

The "William & Harry" scribe noted that "times have changed" since Princess Diana lived in Kensington Palace and Middleton can't take walks in the park like the late Princess of Wales used to do.

"The only place to go is a field where the helicopters land, so you are very imprisoned. Everyone knows what you’re doing and where you are," Seward added.

It was reported earlier this month that despite a potential move to Windsor, Prince William and Middleton will keep Apartment 1A at Kensington Palace as their main London base and retain their estate in Norfolk, Anmer Hall.

An unnamed insider told Us Weekly that the royal couple wanted to move to Windsor to be closer to Queen Elizabeth and the duchess' parents, Carole and Michael Middleton.

Prince William and Middleton's children, Prince George, 8, Princess Charlotte, 7, and Prince Louis, 4, also played a big role in their decision to make the change.

"Charlotte can go horse riding in the open air and George can play football on extensive grounds," the source explained. "Louis loves being close to his great-grandma, and he’s going to take tennis lessons this summer. They're starting over there, and George, Charlotte and Louis are really excited about going to a new school and being in the countryside in the fresh air where there’s lots of space for them to play freely."

Royal correspondent Jonathan Sacerdoti said he believes that the Cambridges' rumored move to Windsor won't affect Prince William's working relationship with Prince Charles.
