Line of Duty fans may have something to hold on to as star Martin Compston has hinted that series seven could be on the cards.

While the beloved BBC crime drama hasn't officially been recommissioned following its series six finale, Compston confirmed the cast has a WhatsApp group chat with a very promising name.

"We have got a WhatsApp group that was 'Line of Duty 6' and a while ago [creator] Jed [Mercurio] changed the name of it to 'Line of Duty 7,'" the Steve Arnott actor said on his podcast Restless Natives.

"What I love about it is we have never spoken about it since," he then said about the show.

"We have had such a good run with it and a bit of you does go: 'Let's walk away on a high' but we all want to work together again because we are so close," he continued, not ruling out a new instalment entirely.

What to Read Next

"We wouldn't do it just for the sake of it. It would have to add to the series, it would have to make the series better."

Compston has previously addressed a possible return of the AC-12 gang for one last series, saying "it is definitely on the table".

In January, the actor revealed he, Mercurio and co-stars Vicky McClure and Adrian Dunbar had met to discuss a potential new chapter. Compston acknowledged that the series has wrapped up nicely, whilst teasing that a new season isn't entirely off the table.

"We had a long talk about it and we all said that we'd be up for doing one more. One last one," he told GQ. "So that's where we're at. That talk was in April and from then nothing's changed. All we've said is that we'd be up for doing one more at some point but none of us have signed on."

Line of Duty is streaming on BBC iPlayer, and DVD and Blu-ray boxsets are also available to buy now.
