Line of Duty season 6 cast: Who will Kelly MacDonald play? Jed Mercurio reveals details

At the time, very little was known about Macdonald’s role on the show and who exactly she would be playing.

Speaking on the Albi podcast, A Stab in the Dark, Line of Duty creator Jed Mercurio revealed more details about Macdonald’s character.

Mercurio said: “Well we have Kelly Macdonald, who plays DCI Joanne Davidson, who is a senior investigating officer on a murder investigation team and she is investigating an unsolved high-profile murder case and her handling of the case creates question marks which bring AC-12 in, the anti-corruption unit, to look at whether the case is being mishandled or misdirected.”

At the end of Line of Duty season five, all the clues and rumours pointed too Ted Hastings (played by Adrian Dunbar) being the mysterious ‘H’ – the corrupt officer working with organised crime syndicates.
