WHAT TO WATCH

THE WALK-IN ITV, 9pm

Stephen Graham knocks another performance out of the park as he plays Matthew Collins, a reformed neo-Nazi now working for the anti-racist organisation Hope Not Hate in Jeff Pope’s riveting five-part drama, based on real events. Using informants (or “walk-ins”), Collins tries to infiltrate National Action – the first far-Right organisation to be banned by the UK government since the Second World War – but isn’t having any success until, in 2017, a year after the horrific murder of Yorkshire MP Jo Cox, he receives an email from inside the organisation, telling him of a plot to kill Lancashire MP Rosie Cooper, and we see his attempts to prevent it. (Cooper has recently announced she is standing down from Parliament, acknowledging that the events had “taken their toll”.)

The drama, which pulls no punches about what attracts some young white men to far-Right politics, plays out like a thriller. Games of Thrones star Dean-Charles Chapman plays National Action leader Jack Renshaw (a convicted child sex offender later jailed for life for plotting Cooper’s murder) and Andrew Ellis is Robbie Mullen, an easily swayed young loner who joins the neo-Nazi group but later becomes an informant for Hope
