THE OTHER ONE

BBC1, 9.30pm

This comedy about the family of a dead man who discover he had a whole other family really gets into its stride in this second series.

Catherine ‘Cathy’ Walcott (Ellie White) and Catherine ‘Cat’ Walcott (Lauren Socha, above) only discovered each other existed after their dad dropped dead. Having finally come to terms with the fact they are sisters, they are now reeling from the news they also have a brother, Callum (Christopher Jeffers). And that Cathy just snogged him. She’s horrified that she has French kissed a sibling.

Cat’s mum, Marilyn (Siobhan Finneran), is also furious to learn she wasn’t Colin’s only mistress.

A cracking cast and a barrage of witty one-liners makes this a must-see.
