Christmas Day is always a milestone occasion for any new royal wife or husband, with locals turning out to see the latest addition to the royal family in their droves in Sandringham.

The late Queen Elizabeth rarely invited partners to stay at her Norfolk estate before marriage, but Meghan Markle was believed to have become the first fiancée to spend Christmas with the royals in 2017.

And then in 2019, Princess Beatrice's fiancé, Edoardo Mapelli Mozzi, also joined his future wife at the Christmas Day church service.
