Line of Duty survey: Who could be H and who might die?

It's almost time for the return of hit BBC crime drama Line of Duty.

The sixth series will see our trio of heroes DS Steve Arnott (Martin Compston), DI Kate Fleming (Vicky McClure) and Superintendent Ted Hastings (Adrian Dunbar) thrown into a new anti-corruption case for AC-12.

The focus of the new episodes will be DCI Joanne Davidson, played by new guest lead Kelly Macdonald.

Joanne has been the senior investigating officer in the unsolved murder of investigative journalist Gail Vella, but her behaviour relating to a robbery has caught AC-12's attention.

Meanwhile, last series ended with AC-12 being made aware that the mysterious high-ranking police officer 'H' is one of four individuals, with the fourth yet to be revealed.

The new series of Line of Duty begins on Sunday night on BBC One (BBC/World Productions/Steffan Hill/Geraint Williams)

As we approach the new series, when is a better time to look back over the previous series.

Of course the first run followed the actions of DCI Tony Gates (Lennie James), while the second saw Steve and co get caught up with DI Lindsay Denton (Keeley Hawes).

Lindsay also returned in series three as Sergeant Danny Waldron (Daniel Mays) took the focus in that set of episodes.

Thandie Newton memorably took on the role of DCI Roz Huntley in the fourth series, while the fifth run focused on the rogue investigations of DS John Corbett (Stephen Graham).

The finale of series five saw Hastings' loyalties questioned, but thankfully that appears to have all been laid to rest...or has it?

APOLOGIES, THIS SURVEY IS NOW CLOSED, BUT RESULTS ARE AVAILABLE HERE.

Well, with those views shared, we just have to sit back and enjoy the seven episodes of twists and turns coming our way.

The sixth run will also introduce new teammate DC Chloe Bishop, played by Netflix's Cursed star Shalom Brune-Franklin.

However, as usual we will have to wonder: can we trust her?
