Line Of Duty season 6: we finally have a return date for the hit series

Posted by for TV

Calling all Line Of Duty fans: a release date for the sixth season of the hit BBC police series has just been confirmed.

After months of sharing teasers, BBC One has finally confirmed when the sixth season of Line Of Duty will land on our screens – and it couldn’t come soon enough for fans. 

Jed Mercurio’s hit police drama, which of course follows anti-corruption unit AC-12 as they catch crooked coppers, is perhaps one of the most addictive ongoing series

So we’re delighted to share the news that it will be returning next month. 

Line of Duty will return on Sunday 21 March at 9pm for its sixth series.

Vicky McClure, Adrian Dunbar and Martin Compston will return as DI Kate Fleming, DS Steve Arnott and superintendent Ted Hastings respectively. Shalom Brune-Franklin will join the cast as new addition to the AC-12 team, DC Chloe Bishop. 

Kelly Macdonald also makes her debut on the show as guest lead detective chief inspector Joanne Davidson, the senior investigating officer on an unsolved murder case whose suspicious conduct attracts the attention of Anti-Corruption.

As previously announced, this series of Line of Duty will comprise of seven episodes, instead of the usual six, which makes it the longest series to date. A new season of the show’s official podcast, Obsessed With… Line Of Duty, will also be released at the same time as the first new episode to accompany the new series.

So, what can we actually expect season six?

Line Of Duty season 6: the cast
DC Chloe Bishop (Shalom Brune-Franklin) will join the cast of Line Of Duty season 6.

Last year, the BBC confirmed that the new series of the show is set a year and a half on from the events of series five. It will feature a brand new case for AC-12, focusing on an enigmatic detective chief inspector.

Speaking on Lorraine, Mercurio gave fans an idea of what they can expect from DCI Joanne Davidson (played by Macdonald).

“Kelly plays DCI Joanne Davidson, who is the senior investigating officer on a high-profile murder that remains unsolved over a year after the killing,” he said. “And AC-12 get involved because there are question marks over her investigation.”

In a BBC interview, Mercurio also called the new DCI “the most enigmatic adversary AC-12 have ever faced”.

Brune-Franklin, who plays AC-12’s newest team member, DC Chloe Bishop, talked about her role with Radio Times, saying: “Being on set as such a huge fan of the show is such a trip-out. I was running around being a fangirl and I don’t know if that’s ever going to wear off.”

While we don’t know what else is in store for AC-12, we just know this is going to be one hell of a series (again!).

Line of Duty will air weekly from Sunday 21 March on BBC One and BBC iPlayer. Series one-five are available to watch as a boxset now on BBC iPlayer.
