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.
“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.”
