Line Of Duty: Everything you need to know about the new season of TV's best cop drama 

Ted Hastings and co return for season six on Sunday. Here's what's in store... 

Line of Duty: Adrian Dunbar as Superintendent Ted Hastings and  Martin Compston as DS Steve Arnott.

Few shows whip their fans into a frenzy like Line Of Duty does. The anticipation surrounding series six of the BBC police drama is immense – heightened, perhaps, because of a delayed air date (filming had to be halted thanks to the Covid-19 pandemic).

You see, Ted Hastings’ famous catchphrases – “Mother of God!” – Jed Mercurio’s clever, twist-heavy writing, and the impressively high calibre of guest stars are just a few elements that make Line Of Duty stand out in the world of TV dramas.
