Call the Midwife
8pm, BBC One
The heartwarming saga of the maternity nurses at Nonnatus House continues for its ninth season. We open in 1965, and the death of Winston Churchill has shocked the nation. The midwives continue to go about their work in the East End, trying to get a heavily pregnant single mother and her son out of squalid accommodation, while Fred finds an abandoned baby in a dustbin and rushes to try to find its mother. Oh, and there’s a competition to win a year’s supply of tights for Trixie, Lucille and Valerie. Ammar Kalia

Doctor Who
7pm, BBC One
Jodie Whittaker and friends settle into their regular Sunday night slot, having launched the new season and, indeed, this eventful two-parter on New Year’s Day.

The Trial of Christine Keeler
9pm, BBC One
The gunplay on Wimpole Mews sees Christine (Sophie Cookson) in court as a witness, but a crafty Sunday Mirror hack thinks she could share an even juicier story. The atmospheric drama based on the scandalous 1963 trial cranks up the tension but also offers glimpses of Keeler’s tough teen years in Staines. Graeme Virtue
SAS: Who Dares Wins
9pm, Channel 4
The gratuitously demanding SAS course returns. Somehow, they’ve found another 25 masochists willing to subject themselves to trial by icy water, sleep deprivation and psychological deconstruction, all under the beady eye of Ant Middleton. This year, the hazing takes place on a remote Scottish island. Phil Harrison
The Wonderful World of Chocolate
