Undercover: Britain’s Homeless Scandal – Channel 4 Dispatches
8pm, Channel 4
You only have to walk around a British city to see that homelessness is on the rise again. In this Dispatches special, Jackie Long investigates the impact on homeless women due to councils struggling to meet their obligation to provide emergency housing. We meet women escaping violence, as well as expectant mothers, some of whom, it’s claimed, are being wrongly turned away. David Stubbs
SAS: Rogue Warriors
9pm, BBC2
Second instalment of Ben Macintyre’s terrific study of the genesis of the Special Air Service. It’s essentially the TV adaptation of Macintyre’s book of the same name, which confirmed that the popular myth of moustache-twirling swashbucklers wasn’t far from reality. This episode reflects on such uninventable characters as Lt Col Paddy Mayne, as volatile as he was courageous, and the regiment’s adjustment to the dispatch to Colditz of its eccentric founder, Col David Stirling. Andrew Mueller
The Halcyon
9pm, ITV
If you’re currently feeling like a character in a big historical drama, well, that’s because you are. Back in the 1940s, some other characters are also having an eventful time, in the penultimate episode of the wartime drama: while Emma is asked to organise the hotel’s half-century celebrations, Betsey falls for a bar-room charmer. Adil attempts to distance himself from Lucien, and MI5 officers turn up at the Halcyon with a search warrant. Ali Catterall
The Art of France
9pm, BBC4
The denouement of Andrew Graham-Dixon’s exploration of French art. In the late 19th century, Paris was transformed into an intellectual and cultural hub, yet the art establishment seemed preoccupied with the past. Cue a fresh wave of artists determined to capture new lives forged by the modern metropolis. Thus, impressionism was born, with Monet, Degas and cohorts eschewing the classical to capture the grit and the glamour of a newly puckish Paris. Mark Gibbings-Jones
The Wedding Day
10pm, Channel 4
Sally, the bride’s mum, doesn’t see the point in a huge wedding. “It’s just one day,” she says, in the knowledge that marriage, the important bit, takes place afterwards. Still, a biggish wedding is what’s planned between her daughter, Serena, and Jordan. This enjoyable fly-on-the-wall documentary unshowily makes its points. Everyone thinks theirs is the only event to have worries and personality clashes. The truth, of course, is that they all do. John Robinson
Girls
10pm, Sky Atlantic
As the sixth and final season of Lena Dunham’s game-changing comedy-drama begins, Hannah is as self-absorbed and flawed as ever. A work trip to a surf retreat sees her ennui and nous for seeking out unsuitable sex buddies collide once again, this time starkly contrasted with Adam and Jessa’s happiness. Although it’s not as fresh as it once was, Girls remains one of TV’s best series – plus there’s a cameo from the brilliant Riz Ahmed. Hannah J Davies
Last Week Tonight with John Oliver
10.45pm, Sky Atlantic
John Oliver’s sterling work during the pre-election period was perhaps only rivalled by that of the dazzling Samantha Bee on US late-night telly. His roundups of how low and ugly the campaigning became were much-required sparks of dark hilarity in the festering gloom. Now, in Mr Trump’s wacky world of alternative facts and ill-conceived executive orders, this much is clear: we need the furious Brummie more than ever. Ben Arnold

Knight and Day (James Mangold, 2010) 8pm, E4
Tom Cruise is an apparently rogue CIA man who pretty much kidnaps vintage car aficionado Cameron Diaz to help him evade the many agents, Feds and crooks out to wrest from his mitts a somewhat Hitchcockian McGuffin called the Zephyr (an eternal-life battery that would make the Duracell bunny weep with envy). Paul Howlett
