Richard Madeley: Inside the World’s Mega Prison
9pm, Channel 5
If you can get over the idea of Alan Partridge being let loose in one of El Salvador’s most controversial prisons, Richard Madeley’s visit to the notorious Cecot is a genuinely chilling experience. He finds thousands of men silently sitting on stacked beds in cells that are lit 24 hours a day. When he asks about conditions, he is told to leave. But after learning more about the nation’s gang history, and how Trump has made use of the prison, Madeley returns … Hollie Richardson

A Taste for Murder
9pm, ITV1
A pair of cheeky vloggers break into the villa of a reclusive film star to find her lifeless body – and soon an investigation is under way, involving plastic surgery and forged passports.

The sparky drama based on Holly Jackson’s series of YA bestsellers returns.

Only Child
9.30pm, BBC One
More from the underrated sitcom about a father and son – think Frasier, but in Scotland. Ken is bamboozled by having to use his phone for everything (he had so much change in his pockets his trousers fell down in Asda) so he asks Richard to help with his QR code train ticket. A fiasco ensues. HR
Peelers: The PSNI for Real
10pm, BBC Two
This documentary series is far too chummy with the officers it follows, and the sight of presenter Stephen Nolan riding shotgun in a cop car is inherently comical – but he does sometimes get results. The climax this week is a surprising ad hoc interview with a career car thief addicted to crack, who this time might be innocent. Jack Seale
