Line Of Duty season six has now been confirmed for 2020 with a brand new trailer.

A brand new video has revealed the likes of Ted Hastings, Kate Fleming and Steve Arnott will be returning to our screens with another series of Line Of Duty this year.

Despite there previously being a two year gap between seasons, the police anti-corruption unit AC-12 is back for another dramatic season in 2020.

So when will the BBC drama air, who is in the cast and how did season five end?

When will Line of Duty season 6 air?

Unfortunately, there isn't a set release date for Line Of Duty season six just yet, but a new trailer for upcoming BBC dramas coming up in 2020 sees a shot of Vicky McClure's Kate Fleming looking over her shoulder.

Director of the series, Jed Mercurio also teased what's to come later this year.

The series writer and creator said: “[A release date is] something that we have at the planning stage, so we are working towards a date. We can’t confirm everything until things are in place."

Who will star in Line of Duty season 6?

We’re hoping fan favourites Ted Hastings (Adrian Dunbar), Steve Arnott (Martin Compston) and Kate Flemming (Vicky McClure) will all be back.

While Martin previously revealed he hadn’t yet signed a contract, by sharing a photo of the script on social media, he confirmed he would be taking part.

Other characters who haven’t yet been killed off include Steve's love interest DS Sam Railston (Aiysha Hart), DCC Andrea Wise (Elizabeth Rider), Hastings' wife Roisin (Andrea Irvine) and PC Tatleen Sohota (Taj Atwal) .

John Corbett (Stephen Graham) was tragically murdered last season so definitely won’t be back, but young gang member Ryan Pilkington (Gregory Piper) is certainly set to return after joining the police at the end of season five.

Meanwhile, Trainspotting actor Kelly Macdonald was announced as a guest lead for the new series, playing Detective Chief Inspector Joanne Davidson, the 'senior investigating officer of an unsolved murder, whose unconventional conduct raises suspicions at AC-12'.

Jed Mercurio said: "We're honoured that Kelly Macdonald will join Martin, Vicky and Adrian in series six of Line Of Duty. DCI Joanne Davidson will prove the most enigmatic adversary AC-12 have ever faced."

Is there a trailer for Line of Duty series 6?

The BBC shared a trailer which sees Kate Fleming looking pensively.

As well as Line of Duty, the teaser also shows clips from Killing Eve and an adaptation of Malorie Blackman's novel Noughts + Crosses.

Will series six be the last series of Line of Duty?

At this point in time, we’re still not sure. The BBC hasn’t commissioned a seventh series yet, but judging by the popularity of season five, it might not be the last we see of the show.

Director Jed previously said: “Once series five has finished airing we’ll have a conversation with the BBC, with a view to whether there’s a possibility to series seven being commissioned. But we definitely know we’ve got series six.”

How did season five of Line Of Duty end?

The fifth run of Line of Duty centred around undercover officer John Corbett who went to extreme lengths to catch head of the Organised Crime Group (OCG) ‘H’.

Corbett’s dangerous mission was uncovered and he faced a grisly end when his throat was slit by the OCG.

It’s thought Corbett’s cover was blown thanks to a tip-off from imprisoned henchman Lee Banks. Ted Hastings then came under fire when it was suspected he was the source who told Banks to get revenge on Corbett for beating his wife earlier in the series.

After a large amount of bribe money was discovered in Hastings’ hotel room, Carmichael then arrested him for conspiring to murder Corbett. However, this investigation exposed Gill Biggeloe for trying to frame Ted.

In the season finale, Hastings returned to duty after a brief suspension, but the identity of 'H' still remains a mystery.

The final eerie scene then revealed one corrupt member of the force is still at large.
