BBC director-general Tony Hall has announced that the police anti-corruption drama will run until series 6

Series four of the BBC1 police anti-corruption drama ended on Sunday, and while we knew it would be back for at least one more run as the huge and complex story arc of police corruption headed towards its denouement, whether it would extend beyond that remained a mystery.

But at an event launching a raft of new BBC drama commissions, Lord Hall told the audience “I am very excited to say there’s not one but two more series of Line of Duty. So hooray for AC-12!”

The announcement will come as a silver lining for Line of Duty fans who recently discovered that they may not get to see the next series until spring 2019.
