Lady Anne Glenconner made the remark when speaking to The Times. Margaret was the Queen’s younger sister. Lady Glenconner was married to Colin Tennant who owned the Caribbean island of Mustique, where Margaret and the Cambridges have taken holidays.
She explained William and Kate were “absolutely splendid” and “just right for the younger generation”.
Lady Glenconner, 87, said: “They said how much they enjoyed Mustique because its so private.
“We've got turtles now and evidently George and Charlotte loved it.
“Nobody bothers them.”

She added: “They're so used to the royal family there that nobody takes a blind bit of notice.”
Lady Glenconner grew up at Molkham Hall, next door to the Queen and Margaret in Sandringham.
She even bathed William and younger brother Prince Harry, the Duke of Sussex when they were young boys.
Mustique is a private island under the jurisdiction of Saint Vincent and the Grenadines.
