About Line of Duty
Line of Duty tracks AC-12, a police anti-corruption unit, through cases that feed one long conspiracy about the identity of H. Martin Compston and Vicky McClure play Steve Arnott and Kate Fleming under Superintendent Ted Hastings (Adrian Dunbar). It aired on BBC Two from June 2012, moved to BBC One for series 4 in 2017, and closed series 6 in May 2021 with 36 episodes.
The BBC confirmed a six-episode seventh series on November 18, 2025, with all three leads returning and filming in Belfast from spring 2026. Trade press points to a 2027 broadcast, with Robert Carlyle reported as the guest lead in February 2026. The exact airdate was still unconfirmed on September 17, 2026, so series 7 sits at the end of the list as a scheduled but unaired entry.
Good to know
Episode counts: 5, 6, 6, 6, 6 and 7. The 2020 Sport Relief sketch is a charity comedy short, not series canon, and is left out. Series 7 credits reported so far (Jed Mercurio writing, Jennie Darnell and Mercurio directing) come from 2025 to 2026 announcements and may change before broadcast.
