Martin Compston, Vicky McClure and Adrian Dunbar reprise their roles as AC-12’s finest, Steve Arnott, Kate Fleming and Ted Hastings, in season seven

This is not a drill! The BBC has unveiled a first look at the long-awaited seventh season of Line of Duty.
The upcoming six-part series, written and created by Jed Mercurio, sees Martin Compston, Vicky McClure and Adrian Dunbar reprise their roles as AC-12’s finest: Steve Arnott, Kate Fleming and Ted Hastings.
The first look photos show the core trio back in action as they take on their most sensitive case so far.
As we count down the days until the show’s return next year, find out all we know about season seven.
What to expect from Line of Duty season 7
In season seven, AC-12 has been disbanded and rebranded as the Inspectorate of Professional Standards.
The synopsis continues: “Anti-corruption work has never been more difficult and in this challenging climate, the trio are assigned their most sensitive case so far.”
Who are the new season 7 cast members?
BAFTA-winning actor Robert Carlyle (Trainspotting, 28 Weeks Later) has joined the cast as Police Constable Shaun Massie, a Specialist Rifle Officer (SRO), a veteran marksman, operating with Tactical Operations Unit 7 (TO-7) to take down Organised Crime Groups.
According to the BBC, Massie is a gruff loner who keeps himself to himself, but when his boss, TO-7’s commanding officer DI Dominic Gough, is accused of being a sexual predator, Massie’s otherwise detached demeanour changes drastically.
Meanwhile, Tom Weston-Jones (Warrior, Sanditon) plays Detective Inspector Gough – a “charismatic officer who has won plaudits for a string of takedowns of organised crime. Gough is accused of abusing his position of trust to act as a sexual predator. But is his case a deliberate distraction from a bigger threat still operating in the shadows?”
Gough’s TO-7 team also includes Laura Aikman (This City Is Ours, Gavin & Stacey) as DC Paula Beckman, Levi Brown (This Town, Girl Taken) as DC Luke Tobin, and Amy Leigh Hickman (Ackley Bridge, You) as DC Nira Rashid.
Further new cast members include David Calder (Motherland, Rivals), Steven Elder (Prisoner, Toxic Town), Dominic Mafham (Vigil, Killing Eve), Aimee Powell (Believe Me, Art Detectives), and Naomi Yang (Under Salt Marsh, Maternal).
Which cast members are returning?
As well as Martin Compston, Vicky McClure and Adrian Dunbar, fans can expect to see a host of familiar faces reprise their roles for season seven.
Mark Bonnar will be back as former Deputy Chief Constable Mike Dryden, alongside Owen Teale (Chief Constable Philip Osborne), Perry Fitzpatrick (DS Chris Lomax) and Christina Chong (DI Nicky Rogerson).
When will season 7 be released?
With filming in Belfast having wrapped earlier this year, season seven will arrive on BBC One and iPlayer in 2027. A specific release date has yet to be announced.
