It's been on our screens since 2012, but series six of Jed Mercurio's hit crime drama Line of Duty was certainly the most-talked about, with viewers finally discovering the identity of H.

The show, which concluded during the tense series finale on Sunday 2nd May, has now broken even more viewing records with that final episode, where AC-12's Superintendent Ted Hastings, DI Kate Fleming and DS Steve Arnott brought down the bent coppers.
