It’s the show that has gripped the nation, with 10.9 million viewers tuning in for last week’s episode ahead of Sunday’s finale.
Yet Line Of Duty star Martin Compston – who plays DI Steve Arnott – has revealed the BBC drama could be coming to an end sooner than everyone thinks.
Martin – who previously revealed that executive decisions about the series are ‘above his pay grade’ – cast doubt on the show’s future during an appearance on The Jonathan Ross Show.
Coming to an end? It’s the show that has gripped the nation, yet Line Of Duty star Martin Compston has revealed the drama could be coming to an end sooner than everyone thinks
In scenes due to air on Saturday’s episode of the ITV show, Martin, 36, said: ‘We won’t come back just for the sake of it. That’s for sure. We’ll come back if there’s a story to tell.
‘If it ends well maybe sometimes it is best to leave it. But genuinely we don’t know.’
The admission comes after Martin teased that fans will get some ‘big answers’ during Sunday’s finale, and admitted he believes it could be the ‘perfect ending’ to the police drama.

Speaking on the Shrine Of Duty podcast, Martin confessed that he thinks Sunday’s episode could be the best way to wrap up the ‘story arch’ – but he refused to rule out another series.
When quizzed on whether viewers will learn who the illusive ‘H’ is, Martin said: ‘I wouldn’t quite go the Jo Davidson no comment route – but what I will tell you is I think there’s a lot of pay offs coming this Sunday.
‘There’s a lot of big answers and it’s deserved, people have stuck with us for a long time, so there comes a point where the story arch comes to an end.’
Martin also touched on whether series seven is likely, after show bosses previously claimed they believed the current season would be the last.

He said: ‘We don’t know [if there will be another] – that’s nothing new. Jed always takes time after a series, like a couple of months.
‘There’s a lot of stuff above my pay grade like analytics and audience scores. He takes the emotion out of it and looks at all that.’
Admitting it could be the ‘perfect ending’, he said: ‘It’s different this year, because we have to look it in terms of, do people want us back? 10 years in you start to think of legacy, and if it goes down that well it might be the perfect ending.’
‘But then we might go another couple of months and… what I will say is we won’t do one just for the sake of doing it. Jed will only do it if there’s a story to be told.’
Omg! Martin confessed that while he thinks Sunday’s episode could be the best way to wrap up the ‘story arch’ – he also refused to rule out another series
The Scottish star revealed the special technique he uses to help learn his lines and make sure his fake accent rings true.
When asked how he manages it, Martin said: ‘It can be hard, that dialogue on its own would be hard anyway, throw the accent in there…
‘The scene we did the other night, 30-pager, trying to juggle the accent at the same time. When we’re away from it for a long time, when I do that voice I can hear him, it’s like a costume.’

Martin saidsomeone records his lines for him to listen to: ‘I walk about all day with him in my ears. It’s just graft. I’m not naturally good at accents. I need to work harder, which then makes me better because I’m not complacent with it.’
He added: ‘If you’re in these scenes with these amazing actors, amazing guest stars, it’s intimidating enough without worrying about the accent. Speaking to the wife and stuff I’ll drop it, I very much stay in it [on set].’
Elsewhere during the interview, Martin discussed how he struggled to fit into his infamous waistcoats after putting on weight during lockdown.

When asked how he manages it, Martin says: ‘It can be hard, that dialogue on its own would be hard anyway, throw the accent in there…’
He said: ‘[I’d] just finished filming The Nest, had my top off a fair bit in that… I’m usually a 32, got down to 30, now I’ve got these tailored suits for Line of Duty.
‘We start filming, lockdown happens, up to about a 34… I couldn’t get them on. I couldn’t even get the shirts buttoned. Two weeks of hours on an exercise bike, eating soup, water… miserable.’
Martin also discussed how he receives some racy DMs and has been offered several proposals – marriage and otherwise.
He said: ‘The Instagram DMs get a bit out of hand… a lot of stuff I wish I hadn’t seen… I need to stop looking at them. A lot of marriage proposals and a lot of proposals of other stuff from both sexes I must say.’
The Jonathan Ross Show airs on Saturday at 9:35pm on ITV, while the Line Of Duty finale airs on BBC One at 9pm on Sunday.
