During Christmas 2010, Kate Middleton was not invited, even after she and Prince William announced their engagement the month before.
This year it is expected that Prince Harry, Prince Charles and the Duchess of Cornwall, Princess Anne and Vice Admiral Timothy Laurence, Prince Edward with his wife, Sophie, the Countess of Wessex, and their children, Lady Louise and James, Viscount Severn will all be joining the Queen at Sandringham on Christmas Eve.
Meghan did not warrant an invite to the festivities last year, as the event is usually reserved for close family.
It is believed that because Meghan is now living in the UK with Prince Harry and her family still lives in the United States, she will take a seat for the traditional festivities with the Royal family, according to royal expert Richard Fitzwilliams.
“In 2010 Kate was not invited to do so after her engagement to William nor was Mike Tindall after his to the Princess Royal's daughter Zara Phillips and only spouses and close family are usually invited," Fitzwilliams said. “However Harry and Meghan will be living together at Nottingham Cottage at Kensington Palace and her family are in the United States."
Breaking away from tradition isn't uncommon for the royal family, however.
“The monarchy relies heavily on precedent and tradition but it also makes its own,” he said.
William and Kate have only missed the royal celebrations once previously, which was in 2012 when Kate was pregnant with Prince George and suffering from severe morning sickness. They rejoined the family on Boxing Day for Prince Philip's traditional Boxing Day pheasant shoot.
With the wedding looming early next year, it is expected that Meghan will be welcomed to the celebrations in the Norfolk home.
"During the celebrations Meghan will get to know the royal family much better,” Fitzwilliams said.
