Tonight's TV highlights

Spooks 9pm, BBC1 Perhaps because it exists in a hyper-real bubble where Britain is always under threat and conspiracies abound, Spooks is an admirably consistent series, an undervalued attribute in TV. That's all the more remarkable when you consider how often its main characters change. Tonight's season nine opener, for instance, finds the team mourning the late Ros Myers and, in Harry's case, getting used to working with a new home secretary. Meantime, there's yet another plot to foil as, on a ship in Tangier, handsome Lucas joins battle with terrorists led by a Somalian al-Qaida operative. Quality hokum. Unequal Opportunities With John Humphrys 9pm, BBC2 This is a thorough look at how poor children in the UK are 25 times less likely to make it to a top university than their private school counterparts. Presented, pleasingly, by Humph, who doesn't pull his punches even when speaking to eager young graduate teachers, where other interviewers might be happy to nod enthusiastically. The Today man speaks to heads of inner-city academies, grand public schools and once-failing comps to try to work out how to narrow the gap. Cherry Gets Married 9pm, BBC3 We've seen her give birth and now we're going to her wedding. Not Katie Price, but likable presenter Cherry Healey, who this week interviews other brides-to-be about their reasons for saying they do. She chats to a 16-year-old who has already moved in with her strangely quiet fiance's family. Then a young woman preparing to become an army wife and a woman who has kept herself unspoilt for her future husband. It's not so much an essay on marriage with a cohesive conclusion, more a series of thumbnail sketches, but no less satisfying for it. Rory And Paddy's Even Greater Adventures 9pm, Five Following their success touring England in a camper van, exploring some of the eccentric and downright violent pastimes practised by the rural denizens of this sceptr'd isle, Rory McGrath and Paddy McGuinness fetch up in Scotland where, if anything, the phenomenon is worse: locals enjoy flounder tramping, mutual stick bashing, haggis hurling and the psychotically dangerous torrent rafting on mattresses. Storyville: The Photographer 10pm, BBC4 In 1987, a customer at a secondhand bookshop in Vienna made an astonishing discovery – a box containing hundreds of colour slides of photographs depicting life in the Jewish ghetto established by the Nazi occupiers of Lodz in Poland. They were taken by Walter Genewein, a Nazi official who served as the ghetto's chief accountant. Dariusz Jablonski's gripping 1998 film measures Genewein's photos against the memories of Arnold Mostowicz, a survivor of the ghetto who has difficulty squaring his horrific memories with Genewein's relatively benign images. Him And Her 10.30pm, BBC3 Not many shows could get us to sympathise with a couple who don't want to go to a party for a little boy who's just left hospital after having leukaemia. Steve doesn't want to go because it's fancy dress. All the pair have got to do is get dressed and warm up some supermarket sausage rolls. Unsurprisingly, even that's beyond them. A great, well-observed sitcom.
