When the news of the show's return was announced last year, Scottish actor Compston said of the news: "Line of Duty has been a job of a lifetime. Not only in terms of the show's success but the people I’ve had the opportunity to work with I now call some of my closest friends.

"I can’t wait to pull the waistcoat on again and get the team back together."

McClure - whose known for roles in This Is England and Trigger Point, added: "It goes without saying I’m so excited Line of Duty is back! Can’t wait to work with Jed, Martin and Adrian again. Belfast, we’ll see you soon!"
