Sue Johnston on Downton Abbey's Christmas Special

One of the Christmas Day TV highlights will be the Downton Abbey Christmas special.

Christmas at the Abbey is never without drama. This year the Crawley family take a trip to Northumberland for the grouse season, while the servants hold the fort back at Downton.

Former Royle family star Sue Johnston joined the cast in the last series and spoke to BBC Breakfast about what it is like to be in the cast.

Downton Abbey is on ITV at 9pm on Christmas Day
