Line of Duty season 7 could be the best yet and it's surely only a matter of time before it's officially announced.

With the latest series drawing to a close in 2021, fans are trying to work out what this means for the seventh series.

With Line of Duty season 6 leaving many questions unanswered it would be a huge shock if we didn't see more episodes. The BBC will be especially keen for a further series given the final episode of season 6 attracted over 13 million viewers.

Star Vicky McClure, who's also to be seen in the new drama Trigger Point, has suggested the cast is up for more episodes.

'Line of Duty' season 7 release date

Line of Duty Season 7 is likely to air in 2023, assuming the BBC orders another series. It’s far too earlier, though, to give an exact start date.

Cast

We expect Kate Fleming (Vicky McClure), Steve Arnott (Martin Compston) and Ted Hastings (Adrian Dunbar) all to return. DC Chloe Bishop (Shalom Brune-Franklin) is also likely to be back. We also suspect that Anna Maxwell Martin will be back as the wonderfully villainous Detective Chief Superintendent Patricia Carmichael

'Line of Duty' season 7 plot

Well, that’s tricky at this point. But we do know now that all of the main players are still alive after the series 6 finale.

It’s also likely to see another star follow in the footsteps of the likes of Lennie James, Keeley Hawes and Kelly Macdonald in playing the show’s chief suspect. 

We can’t imagine the whole who is H thing will have vanished either. And the OCG is unlikely also to have been defeated, so expect more drama there.

Daniel Mays, who played Sergeant Danny Waldron in Line of Duty Season 3, has suggested the whole H plot isn't over.

Appearing on ITV’s This Morning, Daniel Mays revealed that he doesn’t think AC-12 caught H after all! He admitted that he thinks DCI Marcus Thurwell could still be alive and that he could be the one pulling the strings in the OCG!
