The Royle Family returns to the BBC this Sunday for a one-off, hour-long special episode.

It has been nearly seven years since the family sat around the television with a brew and, whilst they have moved with the times, they haven't gone too far from that comfy old sofa and the fag-filled ashtray. The TV is bigger and better with more channels and although much remains the same one thing has, indeed, changed in the Royle household – Nana has moved in and taken up residence with the dining room as her boudoir. With Dave reading her saucy books to her and Denise doing her nails, Nana is the centre of attention which Jim is happy to grumble about, especially when she steals his batteries from his remote control for her fan, leaving him forced to watch Location, Location, Location. However, Nana is too busy stirring up family renditions of Johnny Cash songs to notice.
