EastEnders
7.30pm & 9.30pm, BBC1
The ’Enders Live Week climaxes with the much-anticipated Who Killed Lucy Beale? extravaganza. There will be flashbacks to the night of her death, which gives Lucy (Hetti Bywater) the chance to return, along with Jake (Jamie Lomas) and the high priestess of shambling chic Rainie (Tanya Franks). Part of tonight’s episode is live as the killer is finally revealed and, with the soap at the top of its game on its 30th anniversary and a raft of shifty suspects to choose from, it should be a proper shocker.

The Great British Sewing Bee
8pm, BBC2
This 1950s-themed episode of the crafty contest kicks off with a couture challenge, as the sewers set to work on vintage machines. Christian Dior’s “New Look” spawned innumerable copycats in its day, but how easy will it be to create a similar silhouette? There’s also time to teach some old drapers new tricks, before a blouse challenge that sees the contestants get to grips with delicate sheer fabrics. Claudia Winkleman hosts, with Savile Row tailor Patrick Grant and sewing expert May Martin unpicking the group’s efforts. Hannah J Davies
Reinventing the Royals
9pm, BBC2
Nothing like a mysterious postponement to boost a documentary’s profile. Steve Hewlett’s exposé, originally scheduled to start in January, explores the royal family’s quest to retain public approval while keeping as much as possible private. Squashing inconvenient stories and feeding nice ones is arduous, but one job stands alone as the Kilimanjaro of royal PR: making us like Prince Charles. Hewlett explains how master operator Mark Bolland was hired to forge a new narrative following Diana’s death. Jack Seale
Britain’s Biggest Primary School
9pm, Channel 5
Gascoigne primary school in Barking, east London, currently teaches 1,100 students. This four-part series was filmed over a year at Gascoigne, and it would have been difficult to know where to point the cameras: with a student body from all over the world, for 90% of whom English is a new language, there is no shortage of stories. This second episode focuses on three unusually challenging students and the staff’s efforts to encourage them, and reinforces the belief that whatever teachers get paid it isn’t nearly enough.

Saints And Sinners: Britain’s Millennium of Monasteries
9pm, BBC4
The first of a three-part series charting the evolution of monastic life on and around the British Isles. Dr Janina Ramirez travels to the desolate rock of Skellig Michael off Ireland’s east coast to begin her tour. This is the location of the oldest surviving monastery in the British Isles. Ramirez examines the gruelling lives of the early monks who would eventually spread their hermetic Irish monasticism to Anglo-Saxon Britain. Mark Jones
Ross Kemp: Extreme World
9pm, Sky1
This week Kemp visits Memphis, one of the most segregated cities in the US, and a place where the progress of the civil rights movement has ground to a halt. There he meets pimps, pastors, gang members and police officers, many of whom express despair at the situation facing black people and doubt over whether it can be overcome. Kemp struggles to make inroads into what he describes as a “highly sensitive” subject and, ultimately, is able to offer little more than hope that the imbalance will someday be addressed.

Banana
10pm, E4
Despite neat overlaps with Channel 4 sister show Cucumber, the youth-centric element of Russell T Davies’s triptych of LGBT tales continues to grow in its own right. Last week looked at the consequences of revenge porn, while this episode delivers an equally striking narrative as Freddie’s latest conquest relives the pains of his smalltown upbringing. Student Josh (Luke Newberry) has made a new life for himself amid Manchester’s Grindr-fuelled gay scene, but has he drifted too far from best friend Sophie? Hannah J Davies
