Line Of Duty star Martin Compston played his cards close to his chest as he was quizzed about a new series of the show on This Morning.

The actor, who stars as DI Steve Arnott, was on the ITV show to talk about his upcoming charity football event Soccer Aid, but was also asked about whether the police procedural was coming back.

However, while Compston admitted he and the rest of the cast would “all love to do one at some point”, it seems nothing is official yet.

“Unless you hear anything from us, I’d just leave it at that,” he said.

“There's always rumours, and I am delighted that there's always rumours, that means people want us back and that is a lovely feeling.”

So will there be a seventh series?

We have a look at what we know so far.

When did the sixth series air?

The sixth series of the BBC police drama aired in 2021 and from the minute it wrapped there has been much speculation about whether it would come back for another run.

Fans of the tense TV hit have made it clear they want to see more from AC-12.

Creator Jed Mercurio hasn’t confirmed anything but after the sixth season he told the Radio Times that part of it came down to them “finding new stories to tell within that universe”.

What has been said about the show coming back?

Vicky McClure, who plays DI Kate Fleming, said last year that she’d like to do another series because the sixth was shot during the coronavirus pandemic and she would not want to end like that.

She said on Good Morning Britain: "We've been working together for over 10 years now and you know, the last series was incredible in terms of the response that we got but it was really quite tough to shoot because obviously it was within COVID so it would be lovely to go back and not end on that kind of way."

Adrian Dunbar, who stars as Superintendent Ted Hastings, also dropped a big hint when he shared that he, McClure and Compston were getting together with Mercurio for a meal.

"We are going to have a curry," he said on This Morning.

"We are all just kind of really keen to get back together, we'd all like to see each other again."

But a few months later Compston said on GMB that there was nothing imminent in the pipeline.

“Unfortunately at this point in time there is nothing immediate, there's nothing coming very soon," he said.

What would a seventh series look like?

There are rumours that Line Of Duty could come back for some sort of mini-series.

Dunbar previously teased that a future instalment could air as two 90-minute specials rather than a series of six episodes.

He told The Times: “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.”
