The Prime Minister (played by Elliot Levey)

In The Child in Time, the country's leader remains nameless – and in McEwan's book is genderless, too. We see the Prime Minister in a series of meetings, largely focused on the childcare report, but he also expresses his concern for his colleague Charles as he retreats from public life.

Who is Elliot Levey?

While his biggest role on screen to date is Francesco Pazzi in Da Vinci's Demons, Elliot Levy has done plenty of work on stage, appearing with some of Britain's biggest TV stars: his performances include Brutus in Coriolanus, opposite Mark Gatiss and Tom Hiddleston, and Don John in the 2011 production of Much Ado About Nothing with David Tennant and Catherine Tate. He's also cropped up as the headmaster in Man Down and Ambrose in BBC's Jamaica Inn.

Stephen's mother (played by Geraldine Alexander)

Stephen's parents are concerned about both him and Julie in the wake of Kate's disappearance – but when their son talks of a pub he comes across in Julie's new village, his mother takes a special interest.

Who is Geraldine Alexander?

Geraldine, who plays the older version of Stephen's mother, has appeared on TV screens in Any Human Heart, Marcella and Shetland, as well as guest arcs on EastEnders and Coronation Street.

Stephen's father (played by Richard Durden)

The older Lewis is cynical when it comes to politics – especially about the Prime Minister – but takes an interest in Stephen's reconnection with Julie.

Who is Richard Durden?
