Press Release
Kelly Macdonald is to star in the next series of police drama Line of Duty, as an "enigmatic" DCI whose unconventional conduct raises suspicions.
The Trainspotting star will play Detective Chief Inspector Joanne Davidson, senior investigating officer of an unsolved murder.
Macdonald will join lead actors Martin Compston, Vicky McClure and Adrian Dunbar in the show's sixth series.
Creator Jed Mercurio said the show was "honoured" to have her on board.
"DCI Joanne Davidson will prove the most enigmatic adversary AC-12 have ever faced," he continued.
AC-12 is the drama's anti-corruption branch.
The Scottish actress recently played a bereaved mother in The Victim and can currently be seen as police officer Sarah Weitzmann in BBC Two's Giri/Haji.
The 43-year-old made her screen debut in 1996 as Trainspotting's Diane, the Edinburgh schoolgirl with whom Ewan McGregor's Renton has a relationship.
Piers Wenger, controller of BBC Drama, described Macdonald as "one of the UK's most versatile actors".
"We're excited for viewers to see what Jed's scripts have in store for her when she joins the Line of Duty team."
Thandie Newton, Stephen Graham and Keeley Hawes are among other "guest leads" on BBC One's hit drama.
