10pm, Channel 4“Play off your cerebral wotsit. We can make shitloads of money.” Drug dealer Ewen (Ryan McParland) has spotted an opportunity. Can he persuade Rosie Jones’s skint charity worker Emily to go into partnership with him? After all, he points out, as a disabled woman she’s effectively invisible. It’s a neat premise to underpin this sitcom (co-created by Jones and Peter Fellows) and entirely consistent with Jones’s screen persona, which balances rage, charm and gleeful transgression. It’s also a smart dig at a broken system that routinely writes off disabled people’s capacity to be autonomous, economic actors but still forces them to beg for state support. Funny and pointed.Phil Harrison

9pm, U&DramaThe weird allure of the scandalous Mitford sisters never wanes. This drama is narrated by Nancy (Bessie Carter); through her eyes we view the escapades of her siblings who dallied with fascism, communism and most points in between. It’s fun … albeit fun that flirts with the idea of Oswald Mosley as simply a bit of a bounder.PH
