The Split Up
9pm, BBC One
A spin-off from Abi Morgan’s The Split, this is another glossy divorce drama with the same soapy beats – and more lawyers who have a better handle on their clients’ relationships than their own. Aria is expecting to inherit her family’s Manchester firm from her bereaved father; it’s why she’s been putting off her own wedding for 10 years. But an old flame, a high-profile case with a podcasting couple and the discovery of an affair soon change her course. Hollie Richardson
