Stacey Dooley: Costa del Narcos
9pm, BBC Two
Dooley heads for the sun and sea of southern Spain in this new documentary. She isn’t beginning a travelogue, though, but rather investigating how the area has become the gateway for class A drugs being smuggled into Europe. As turf wars between gangs have caused a surge in violence in recent years, the Spanish police have begun a rigorous crackdown and Dooley joins them on an air force patrol, as well as meeting an undercover officer who takes her on a night-time raid.

With the 2020 London marathon postponed until October, this special looks back to the first race in March 1981, which was completed by more than 6,000 runners. To the backdrop of an almost skyscraper-less London, we relive the men’s final, which ended in a nail-biting dead heat. AK
Reasons to Be Cheerful With Matt Lucas
7.30pm, Channel 4
Already a lockdown hero since his Thank You Baked Potato charity anthem, Lucas now teams up with Harry Hill to showcase the DIY entertainment that has been keeping citizens amused in their homes. That means daft sketches, celebrity guests and the odd cameo by a nosy pet. Graeme Virtue

The travellers are approaching the final stretch, with 4,800km to go until they reach Ushuaia in Argentina.

Primates
8.15pm, BBC One
This three-part ape compendium, narrated by Chris Packham, begins in diverting style.

Film choice
Bernie, 7.05pm, AMC
Richard Linklater’s curious and compelling drama re-enacts a real-life killing while exploring, mockumentary-style, the small-town life of Carthage, Texas. Jack Black is unusually prim as Bernie Tiede, the near-saintly mortician who, mystifyingly, shoots dead the meanest old woman in town, played by Shirley MacLaine. Paul Howlett
