A new series of Line of Duty may be on the cards, according to the BBC.
Charlotte Moore, the BBC's chief content officer, said in a statement: "Addictive event television, Line of Duty has kept the nation guessing for the last seven weeks, so it's no surprise that last night's jaw dropping finale set a ratings record.
"Jed Mercurio is a master of his craft, and I would like to congratulate him and the entire cast and crew for delivering such an incredible drama series.
"I'm looking forward to having a conversation with the team about where we go next and what the future of the series might be."
Ahead of yesterday's divisive season six finale - which finally revealed the identity of 'H' or the 'Fourth Man' - stars Vicky McClure and Martin Compston said they 'genuinely' don't know if there will be a seventh season or not.
Speaking on The Jonathan Ross Show, McClure said: "Genuinely don't [know]. We don't know anything, not just saying it for effect."
Compston added: "That's nothing different for us. Jed always takes months after... there's stuff above our pay grade, analytics, figures and all that kind of thing that comes in. He always takes time off.
"But I think it is important to say, I think this natural story arc that we've been on for the last six years..."
To which Ross pointed out: "That's coming to an end."
Compston continued: "We won't come back just for the sake of it. That's for sure. We'll come back if there's a story to tell. But, so as well, if it ends well maybe sometimes it is best to leave it. But, so, genuinely we don't know."
Compston, who plays Detective Sergeant Steve Arnott in the hit show, also posted on Twitter yesterday to say it had been 'a job of a lifetime', before thanking fans for their support over the years.
Meanwhile, McClure, who stars as Detective Inspector Kate Fleming, shared an 'emotional' statement that said the audience support has been 'unreal'.
"It's not lost on me how lucky I am to be a part of Line Of Duty," she said.
"Not just because of the success of the show but the life long friendships we've all gained.
"We have such a talent and caring crew. A huge part of its success is down to them. Our amazing star guest Kelly MacDonald! Shalom, Perry, Anna, Tommy, Rosa, Greg, Anneika, Nigel, Ace, Liza, Amy to name just a few of the incredible cast in series six.
"Belfast, our LOD home. Thanks for craic as always.
"Honestly, I can't thank you all enough for your love and dedication to the show.
"Raising my brew to you Jed Mercurio! The epitome of honesty and integrity. Martin Compston and Adrian, I love yous 29! Now... let's wrap this up."Featured Image Credit: BBC
