In a move that has sent shockwaves through British television, the BBC has officially confirmed the long-rumoured return of Line of Duty with a seventh series. The announcement, made on February 17, 2026, ends years of fan campaigns, petitions, and frustrated speculation following the divisive 2021 finale of Season 6. Writer Jed Mercurio, creator and showrunner of the acclaimed police corruption drama, has promised a storyline that directly confronts the unresolved questions and criticisms that have haunted the series since its last episode aired.

The new season — expected to consist of six episodes — will resume the hunt for the elusive criminal mastermind known only as ‘H’, the figure whose identity was controversially revealed (and heavily debated) in the Season 6 finale. Mercurio has described the return as “unfinished business” and a chance to “honour the fans who felt let down while delivering the tension and twists they’ve always loved.” In a statement released alongside the confirmation, he said: “The finale divided people — that’s the nature of big reveals. Series 7 isn’t about rewriting the past; it’s about exploring the consequences of what we did reveal, and uncovering layers we deliberately left buried.”

The decision to revive Line of Duty comes after sustained fan pressure. The 2021 finale — which saw the unmasking of ‘H’ as Chief Superintendent Patricia Carmichael — was met with widespread disappointment, with many viewers feeling the long-running mystery was resolved too neatly or unsatisfyingly. An online petition demanding a follow-up season garnered over 150,000 signatures, while cast members Vicky McClure (DS Kate Fleming), Martin Compston (DS Steve Arnott), and Adrian Dunbar (Superintendent Ted Hastings) have repeatedly teased in interviews that “the story isn’t over.”

All three leads are confirmed to return, alongside a mix of new and returning faces. Keeley Hawes is expected to reprise her role as Carmichael, while fresh casting announcements are anticipated in the coming months. Mercurio has hinted that the new series will delve deeper into the fallout of Season 6: internal AC-12 tensions, the lingering influence of organised crime, and the personal toll on the team after years of battling corruption. “We’re not just reopening the ‘H’ case,” he said. “We’re asking what happens when the system you’ve spent your life trying to fix turns on you.”

The revival also addresses real-world changes. The original series ran from 2012 to 2021 on BBC One, becoming a cultural phenomenon with its intricate plotting, shocking twists, and signature interview scenes. It regularly drew audiences of over 10 million and sparked water-cooler conversations about police accountability. The long hiatus was attributed to Mercurio’s commitments to other projects (Bodyguard, Vigil) and the cast’s busy schedules, but fan demand ultimately proved decisive.

Filming is scheduled to begin in spring 2026, with a likely broadcast window in early 2027. The show will retain its signature style — long, tense interrogation scenes, moral ambiguity, and a willingness to kill off major characters — but Mercurio has promised “a more personal, more emotional” tone to reflect the passage of time and the toll on the central trio.

The announcement has been met with ecstatic fan reaction. Social media is flooded with celebratory posts, memes reviving classic lines (“Mother of God!”), and renewed calls for justice for fans who felt the original ending let them down. “This is the redemption we’ve been waiting for,” one viral tweet read. “Bring back the tension, the twists, and Hastings’ moustache.”

For a series that once redefined British television with its intelligent, high-stakes storytelling, Line of Duty Series 7 is more than a revival — it’s a reckoning. The hunt for ‘H’ may have ended in 2021, but the questions it raised — about corruption, loyalty, and the cost of truth — never went away. Now, with the team back together and the stakes higher than ever, the AC-12 faithful are ready for one last ride.

The wait is almost over. The bent coppers better watch out. Because AC-12 is coming back — and this time, they’re not leaving any loose ends.
