Line of Duty Season 7 may seem a long way off, but it’s never too early to start speculating!

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

Line of Duty Season 7 hasn’t even been officially confirmed, but the BBC has revealed it's set to have talks with creator Jed Mercurio over future series. 

With the latest series 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.

Line of Duty Season 7 release date

Line of Duty Season 7 is likely to air in 2022, assuming the BBC orders another series. It’s far too earlier, though, to give an exact start date.


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.

Line of Duty Season 7 trailer

Way too early for a trailer at the moment as filming is yet to begin. However, it will be eagerly-anticipated especially after all the clues in the series 6 trailer. For example fans reckoned that Kate must survive the shooting in episode five of series 6 because she was seen in a piece of the trailer which at the time had yet to air meaning she must be alive. And they were proved right!
