Still Open All Hours, BBC1, 7.30pm
The new series of the revamped sitcom starts with a festive special that finds Granville (David Jason) facing being left alone at Christmas as all his friends and neighbours make plans to go away.

He is particularly dismayed to see Mavis planning a Christmas break with Madge, and terrified to learn Mr Newbold is plotting an escape from Mrs Featherstone’s advances, and leaving Granville at her mercy. To make matters worse, the wily shopkeeper has a consignment of dodgy Christmas crackers to sell and a distinct shortage of customers.

There is even a chance to make new friendships.

Attenborough and the Empire of the Ants, BBC2, 9.30pm
Winter in the Swiss Jura Mountains. A region where it seems nothing lives in the frozen landscape.

However, hidden beneath the snow, billions of individuals are about to stir, because this glittering winter wonderland is home to hundreds of nests of wood ants. Each resident is hunkered down in the corridors and chambers of tiny cities, hibernating through the worst of the cold, barely moving. However, when the snow begins to melt, their lives will change dramatically.

As spring arrives, David Attenborough introduces viewers to the protagonists of a spectacular story – the queens and workers of an incredible ant society. It’s an epic journey.
