Line of Duty is coming back to our screens for a hotly anticipated fifth series about police anti-corruption unit AC-12.


Jed Mercurio’s acclaimed thriller is lauded by viewers for the intricacy of its plot and its nail-biting interview scenes.

Here’s everything you need to know about series five…

When is Line of Duty series five on TV?

CONFIRMED: Line of Duty series five will begin on Sunday 31st March 2019 on BBC1.

The BBC confirmed the news with a mysterious new poster, with stars Martin Compston, Adrian Dunbar and Vicky McClure linked together with handcuffs.

“Crime needs an inside man,” the poster declared.

The latest series of Line of Duty began filming in September 2018, and the cast expected an air date to come at some point in spring 2019.

Speaking in September 2018, series creator Mercurio said: “With Line of Duty we’re shooting series five now, and series six has been commissioned which we’re gonna shoot hopefully in the next couple of years.

“So yeah Line of Duty should be on air, series five early in 2019.”

Star Martin Compston revealed in December that he expected the new series to air in April 2019 – his prediction ended up just one day out.

“I think round about April probably,” he said on ITV’s Lorraine. “We just finish it and then we hand over to the BBC scheduling gods, but I think April has sort of been the time that they normally put it on.”

Is there a trailer for Line of Duty series five? 

YES! Finally, here’s the trailer for Line of Duty series five…

We’ve also had this teaser…

What will happen in the new series? 

The end of series four saw Line of Duty’s network of “bent coppers” revealed itself to be even larger and more complex than AC-12 could have imagined, and they realised they had only scratched the surface of police corruption.

Star Martin Compston has already teased that the script is “immense” and Mercurio said the new episodes feel like “very fresh territory”.

He revealed: “There are things we haven’t done before, characters we haven’t seen before and that I think’s part of the construction of the series.”

Take a look at the trailer and you get a few clues as to what he’s hinting at – including an ominous shot that appears to show Ted Hastings standing in a prison cell. The pressure is clearly on as we see not just one balaclava man but a whole gang, headed up by Stephen Graham’s John Corbett, with three police officers murdered in a hijacking.

It also looks like – with the pressure on – some tension is emerging between the AC-12 gang, and Steve Arnott shown held at gunpoint.

Who will star in series five?

Adrian Dunbar, Vicky McClure and Martin Compston are confirmed to be reprising their roles as the officers of AC-12.

A first-look image has also been released, revealing “Balaclava Man”John Corbett (Stephen Graham) and Lisa McQueen (Rochenda Sandall) in a teaser for what’s to come in series five…

Will there be a sixth series?

Yes, Line of Duty has already been commissioned for a sixth instalment, which is set to film in the next couple of years.

What else has Jed Mercurio been working on?

It’s been a long break since the last series of Line of Duty, but writer Jed Mercurio has kept himself busy with his BBC1 smash hit Bodyguard starring his Line of Duty actress Keeley Hawes and Richard Madden. Charting bodyguard David Budd and his protection of Home Secretary Julia Montague, the series has made a splash around the world – and earned Madden a Golden Globe.


Line of Duty will return to BBC1 in early 2019
