Who Should We Let in? Ian Hislop on the First Great Immigration Row
9pm, BBC2
With “concerns” about immigration as high as ever on the political agenda, Ian Hislop looks back at the history of Britain’s response to outsiders coming here. Extraordinarily, it turns out our Victorian forebears were far more open-minded about immigrants, believing in an open-door policy as a matter of principle. Only when migration levels rose at the end of the 19th century did a backlash begin. David Stubbs
Kat and Alfie: Redwater
8pm, BBC1
It’s all gone a bit murder-mystery as Kat Moon’s quest to find her long-lost son reaches its climax. The odds of her boy Dermott coming out of this well are reduced as Peter’s still missing after a row and the loose ends of Lance’s death are about to be wrapped up. Kat has never been a character regularly granted happy endings, so perhaps the best she can hope for here is to make it to the closing credits without being killed off. Hannah Verdier
The Supervet
8pm, Channel 4
People love their pets. They really love their pets. You won’t understand quite how much until you’ve heard the story of the woman who travelled all the way from Romania to seek the counsel of Noel “The Supervet” Fitzpatrick. Or looked deep into the puppy-dog eyes of a golden labrador facing a total shoulder replacement. Whether you can emotionally invest in the daft hound that collided with a plant pot is, however, a judgment call. Ellen E Jones

Heroes of the Somme
8pm, Yesterday
Of the many questions raised by any study of the battle of the Somme, the most intriguing is: why did it continue? What impelled men to keep walking into a massacre? This documentary seeks an answer by focusing on the actions of seven men who went sufficiently above and beyond duty’s call to win the Victoria Cross. It’s deftly illustrated with archive footage, plus interviews with historians and descendents of the fallen. Andrew Mueller
Killer Women with Piers Morgan
9pm, ITV
Piers Morgan meets Rebecca Fenton, serving life without parole but protesting her innocence. In 2008, she entered her Florida home to find the house ransacked and her husband lying in a pool of blood. Police believed it to be a home invasion by an unknown assailant, but eventually convicted Fenton. It’s compelling, but then the lowest common denominator of true crime can travel comfortably across the Atlantic. John Robinson
Host the Week
9pm, Channel 4
The concept for this new show is that each week it will presented by a different celebrity guest. The twist comes in that they have had no rehearsals, haven’t seen a script, and basically have no idea what’s going on from one moment to the next. Comics and improvisers will guide said celeb through everything from their opening monologue to sketches and interviews. First up, it’s Scarlett Moffatt from Gogglebox, and best of luck to her. Ben Arnold

Riviera
9pm, Sky Atlantic
Adrian Lester has a ball reprising a mildly tweaked version of the charming, shady art dealer persona he inhabited in Hustle as this glossy drama continues. It turns out that Robert Carver (Lester) had been in regular touch with Constantine Clios during the period leading up to his death, and – as Georgina Clios (Julia Stiles) is beginning to realise – that doesn’t reflect well on her late husband. Good fun, so long as you have the requisite pinches of salt to hand. Phil Harrison
Film choice
The Shawshank Redemption (Frank Darabont, 1994) 9.15pm, ITV4
After a gentle start at the box office, Darabont’s cinema debut rapidly grew into an all-time favourite, maybe because – although it contains all the cliches of jail drama – it breaks free to create a rich, life-affirming tale of comradeship in the harshest conditions. Tim Robbins stars as accountant Andy Dufresne, an innocent incarcerated in the brutal Shawshank prison; Morgan Freeman is Red, who befriends him. Paul Howlett
