Meghan and Harry at palace for festive lunch

The Queen has hosted Prince Harry and his fiance Meghan Markle at Buckingham Palace for the Royal Family’s annual Christmas lunch.

The event traditionally takes place each year before the Queen leaves for her private Sandringham estate to spend the rest of the holidays.

The Suits actress, 36, has already been confirmed as part of the Royal party at Sandringham for Christmas.
