Vicky McClure (DS Kate Fleming), Martin Compston (DS Steve Arnott), and Adrian Dunbar (Supt. Ted Hastings) are all confirmed to be returning, as well as Maneet Bindra (Maya Sondhi), Polly Walker (Gill Biggeloe), Andrea Irvine (Roisin Hastings), and Aiysha Hart (DS Sam Railston).

Meanwhile, Stephen Graham will play a baddie who is a person of interest for AC-12.



The fifth series will see a significant format change as – instead of focusing on a single corrupt police officer – the show will focus on an "organised crime group".

"That is the fresh ground that we break in the series," creator Jed Mercurio teased earlier this year.

"We've had these shadowy figures, 'the Balaclava Men', who are part of an organised crime group and have featured on and off all through the previous four seasons. But we've never really gone behind the mask and identified them as proper characters and found out about them."

Line of Duty series 5 begins Sunday, March 31 at 9pm on BBC One.
