The highly anticipated seventh season of Line of Duty is confirmed to begin filming in Belfast in Spring 2026, with a six-part series planned. The return of the beloved police procedural will see the central trio – Martin Compston as Steve Arnott, Vicky McClure as Kate Fleming, and Adrian Dunbar as Ted Hastings – back in action.
