Line of Duty series 7: Everything we know so far

Will we see the return of AC-12?

Author: Emma DoddsPublished 4th Mar 2024

Since it first hit our screens back in 2012, Line of Duty has amassed legions of fans, with six series of the much-loved show airing in total. The gripping sixth series aired in 2021, where viewers finally found out the identity of H.

Series six was believed to be the last series of Line of Duty, so a seventh season of the show might be unlikely. However, there have been an array of rumours about a possible seventh series over the years, so fans are hoping we may get to see more in the future. Here's everything we know, from cast hints to what creator Jed Mercurio has to say...

Will there be a seventh season of Line of Duty?

Series six of Line of Duty was believed to be the last, so it doesn't look to be likely at the moment. However, back in October 2021, reports seemed to reveal the show had been renewed for another series - but this was not confirmed by the BBC.

A source told the Daily Star at the time: “Another series is happening. This is the news millions of fans have been hoping for. A lot of stuff still needs to be agreed and it is likely to take a while. Fans will probably have to wait a few years before it airs on TV.”

What has been said about Line of Duty series 7 so far?

Jed Mercurio

In March 2021, writer Jed Mercurio told the Radio Times: "We’re in a situation where it’s not entirely clear that there will be a seventh series. We would hope there could be. But we’re having to do our planning coming out of COVID, and a whole bunch of other things around the idea that these things aren’t guaranteed at all now.

"Since probably season four, we’ve been talking to the BBC about the realistic longevity of the series. I’ve experienced broadcasters pulling the plug while we were still developing a storyline –Bodies and Cardiac Arrest both ended prematurely on the BBC. So it’s an ongoing discussion, is all I can say. A lot of it depends on the key creatives – me and the main actors – finding new stories to tell within that universe."

Jed also spoke about a seventh season of the show back in 2019 at a press screening of the fifth season: "I don’t know. We all love making the show. I think a lot depends on how people respond to it. I think that it’s great that people get very excited about it, when they get to the end of the series and they talk about what they want to know, and what they want to see next.

"But I think we recognise that it’s got a life span, so I think we’ve got to calibrate that against the audience responses. I have some thoughts (about how it’s all going to end)."

Martin Compston

Scottish actor Martin Compston, who plays the role of DI Steve Arnott on the show, has also kept us all guessing, seemingly hinting that series six could have been the last, before sparking more hopeful season seven rumours.

Speaking on the Shrine of Duty podcast, Martin said: "You know, people have stuck with us for such a long time. I think there comes a point where the natural story arc that's been running all these years is coming to an end."

Although he did go on to admit the cast and crew 'genuinely' don't know about the show's future, we are hoping for the best!

But Martin later got fans talking when he gave a more promising update, while picking up the Special Recognition Award at the 2021 National Television Awards. Accepting the show's second gong of the night, following the award for Returning Drama, Martin excited fans as he said: "We genuinely don't take this for granted and who knows, maybe we'll be back again..."

In 2023, Martin gave fans another promising update, revealing that the cast of the show are in a WhatsApp group chat with Jed Mercurio. Speaking on his Restless Natives podcast which he hosts with Gordon Smart, Martin said: "Well we would love to but at the moment there's no news.

"There's absolutely no immediate plans. Jed's on strike. We're all filming different stuff. We've got a WhatsApp group that was 'Line of Duty 6' and then a while ago Jed changed the name of it to 'Line of Duty 7'. And what I love about it is, we've never spoken about it since!"

Vicky McClure

Back in January 2022, Vicky McClure gave us all another glimmer of hope as she hinted that her and her co-stars were all keen to return for the show. Speaking to The Guardian, the actress was quizzed on whether or not we can expect a Line of Duty series seven, to which Vicky responded: "I don't know! I don't know, there's no word of it."

However, the star then offered us a promising update as she continued: "I think we've all been really honest and said should that happen, we're all game. I'll just stick with the guys. I think when it comes to a close, it will be a natural close for us all."

In June 2022, Vicky then re-ignited the season seven rumour flame as she shared an image alongside her Line of Duty co-stars Adrian Dunbar (Superintendent Ted Hastings) and Martin Compston (DS Steve Arnott), as well as the show creator Jed Mercurio.

As the gang reunited for a catch-up, fans were quick to question whether they could be discussing a potential seventh series!

Heading to the comments, one fan asked: 'Does this mean we have series 7 in the works? Jed did say he wanted to finish on 7', with another optimistic fan commenting: 'Mates discussing a season 7 script perhaps??😃'.

Adrian Dunbar

In November 2022, Adrian appeared on ITV Daytime show Lorraine, where he revealed he'd love to reunite with his Line of Duty co-stars.

When Lorraine Kelly asked: "Do we think perhaps if we can get you all in the same room, you might do another one?", Adrian said: "Yes, there is every possibility. We're all keeping our fingers crossed that we'll hear something at some point. We all want to get back together again. We'd love to go back to Belfast again.

“The last time we did it it was in lockdown, so we were all in bubbles. We couldn't get out… everything was shut. So we'd like to get back to Belfast for a bit of fun.”

Adrian has also previously spoke of a potential seventh series, saying in August 2022: "There’s a big appetite for more Line of Duty.

"It could be three or four episodes, I don’t think there’s going to be six for some reason. It might be two 90 minutes. But it’s all entirely down to Jed what the storyline is going to be. It’s a big ask for him."

When will series 7 be released?

It'd have to be confirmed first before we could start speculating on release dates. Nothing has currently been announced by the BBC, but fans would definitely love to see series seven happen!

Who will be in the cast?

Since we don't know if it's actually going ahead yet, ANYTHING could happen with the characters. But here are a couple of the major players and where you might know them from...
