This year’s festive episode rejoins the Crawley family and their servants six months on from the end of series four and there’s not a pair of mittens in sight.
The two-hour special sees the lot of them up head to their previously unseen London residence, Grantham House, as they prepare to present Rose to the king and queen at Buckingham Palace as part of her ‘coming out’.
And Cora’s mother, Martha Levinson, is back from New York and this time she’s brought her nightmarish son Harold – and both make quite an impression with London’s high rollers.
But as Carson treats the staff to a special day out things turn murky for the Crawleys when they’re implicated in a scandal that threatens to engulf them and monarchy.
The Chritsmas special will air on Christmas Day at 9pm on ITV.
