Line Of Duty: See the cast from series 1 to 6
How have Ted, Kate, Steve and the gang changed?
Can you believe we've almost been watching Line Of Duty for a whole decade? The first season came out in 2012 and we've been addicted to Kate Fleming, Ted Hastings and Steve Arnott ever since. The AC-12 unit were back on our screens with season six, helping us to piece together who 'H' is and what happened to Gail Vella. There were SO many questions; is Jimmy Lakewell involved? Who's Lee Banks again? Could Patricia Carmichael have something to do with it?
