This eye-opening house-swap show, which explores Britain’s wealth divide, returns for a new series. Multimillionaire Barrie and husband Scott hand over the keys to their £6 million mansion, which comes with a private chef and chauffeurdriven Rolls-royce – nice for some, eh? – to Ocean, a single-mum from Essex who survives on £60 per week with her eight-year-old daughter. Ocean dreams of opening a Caribbean food business, and tries to impress Barrie’s demanding friends with her culinary skills. This emotional episode ends with a very big surprise.

★★★ ‘I am attempting in my own modest way to get Julian out of the s***,’ says the straight-talking John Shipton, father of Julian Assange, in a documentary that depicts the realities of the campaign to free the controversial Wikileaks founder (above). It focuses on the relentless work of Shipton – a fascinating character who’s both abrupt and intelligent – as well as Assange’s then fiancee, Stella Moris, who join forces to advocate for Assange on the global stage. Assange, who is currently in London’s Belmarsh prison, faces a 175-year sentence if extradited to the US. Whatever you think about his actions, this is a thoughtful portrayal of a family taking on the Goliaths of the world to save someone they love.
