Kate Middleton is concerned about leaving Queen Elizabeth alone.

According to a source, Kate Middleton is preparing to relocate Queen Elizabeth adjacent to her Kensington Palace home following the incident at Windsor Castle.

According to Express.co.uk, a royal Insider said, “If someone thinks that William and Catherine should move in next to the Queen, that’s entirely reasonable, but if somebody recommends that the Queen should move in next to the Cambridges, that’s something extremely difficult to believe.”

“However, according to the latest report, it was the Duchess of Cambridge who suggested Her Majesty move in to live next door to William and her amid concerns about security for senior members of the Royal Family,” added the source.

It added:

“Prince William his wife Catherine and their children Prince George, Princess Charlotte, and Prince Louis all live at the same address, apartment 1A in Kensington Palace.

“A source has suggested Her Majesty downsizes and moves into the empty apartment next to theirs at Kensington Palace.”

“It makes perfect sense really,” said the source, “with Prince Philip gone, she’s rattling around Buckingham Palace and Windsor Castle, which due to its sheer size is terribly difficult to protect alone.”
