One Day in Southport
9pm, Channel 4
It’s been a year since a 17-year-old attacked a Taylor Swift-themed dance class in Southport and murdered three young girls. It sparked riots across the nation, fuelled by extreme-right rhetoric and online misinformation. This documentary tells the experience of a family whose daughter survived the stabbing, who condemn the nature of the rioting. It also examines the bigger societal problems the riots exposed.

Unforgivable

Jimmy McGovern’s feature-length drama about what happens when a man who sexually abused a young boy in his own family leaves prison is almost unbearably painful to watch at times. Anna Maxwell Martin, Anna Friel and David Threlfall star. HR
Mr Bigstuff

Danny Dyer won a TV Bafta for his comedy chops in this sibling sitcom – and within the first five minutes of the second series, he proves why, while wrapped in a dressing gown.

The Blitz With Rob Rinder & Ruth Goodman
9pm, Channel 5
This series explores notable historical events through the prism of class; this time Rob Rinder and Ruth Goodman are reconsidering the blitz. It’s frequently presented as a horror that affected rich and poor alike; but was that really the case? What they find is an elite, insulated by wealth even, with the country on its knees.

The Walking Dead: Dead City
10pm, Sky Max
We know the streets of zombified New York are ruled by Mad Max-style feudal gangs, but what’s the deal in Central Park? Maggie (Lauren Cohan) and the rattled remnants of the New Babylon raiding party are about to find out, although the fact that none of their enemies seem keen to pursue them into the greenery does not bode well.
