Anna Maxwell Martin returning to Line of Duty

The actor will return as Detective Chief Superintendent Patricia Carmichael in episode five of the current series of Line of Duty.

Viewers will remember no-nonsense DCS Carmichael from series five, where she was brought in as an independent investigator from AC-3 after suspicions mounted over the integrity of Superintendent Ted Hastings.

Now with Ted’s forced retirement looming, is Carmichael in position to take control? And with the restructure of the anti-corruption units, is this the end of AC-12?

Speaking about returning to Line of Duty, Anna Maxwell Martin said "Pat’s back, I can’t remember what she’s doing there, nor would I be allowed to blab, but suffice to say she’s got some new clobber and she’s ready to bust some balls."

Line of Duty continues Sunday at 9pm on BBC One
