Typically, non-royals do not spend the night at the Norfolk estate, and while Middleton's family has attended church with the royals on Christmas morning, they have not spent the night.
Mr Markle was due to walk his daughter down the aisle but pulled out at the last minute after it emerged he had staged paparazzi pictures in the days prior to it.

Meghan and Harry will wait a number of days before they reveal the newborn's name, it has been claimed. "I do fervently pray that you'll all do your utmost to work together in the coming year to make real, substantial progress", he said.
Doria introduced herself to guests on the day as "Meg's mom".
