Eurovision Song Contest
2018 8pm, BBC One
Touting his finely calibrated blend of enthusiasm and eye-rolling disbelief, Graham Norton is once again our guide to Eurovision’s endlessly bizarre cocktail of Euro-cheese and barely disguised geopolitical tetchiness. This year, Portugal is taking the hosting strain after a somewhat unlikely triumph in Kiev. Britain’s entry (by SuRie) is unremarkable but, let’s be honest, at the moment, we could bust out the new Beatles and still finish 14th. Best to set aside partisanship and enjoy this absurdist spectacle while we still can. Phil Harrison
When Harry Met Meghan
7pm, Channel 4
An exploration of the life, character and family history of Meghan Markle before she marries the people’s prince next Saturday. As the child of film industry parents who divorced at a similar age to Harry’s, Meghan’s formative years uncannily resemble those of her royal suitor. Candice Carty-Williams
Harry Hill’s Alien Fun Capsule
7.30pm, ITV
An alien invasion is imminent but Harry Hill, along with celebrity guests including Moira Stewart and Kara Tointon, can save the world. It’s a weird premise but with a sprinkle of Hill charm it works a treat as two teams bring clips funny enough to convince the aliens to spare them. Lovably daft. Hannah Verdier

Mark Gibbings-Jones

Salamander
9pm, BBC Four
Having told Sofie he was a member of Salamander, petty criminal Jamie wants to go straight. But how to meet Paul and hand over the flash drive without the attentions of shadowy forces? The Belgian thriller concludes with a double bill that, like much of the series, over-stretches credulity. Jonathan Wright
TV film
Men & Chicken, 11.15pm, Film4
Queasy Danish comedy in which Mads Mikkelsen and David Dencik are slightly unusual half-brothers Elias and Gabriel, who discover they are the offspring of a geneticist living on a remote island with their half-siblings. There, in a crumbling mansion, all manner of macabre tomfoolery unfolds. Paul Howlett
