The hit BBC police corruption drama's writer - who is currently working on the highly-anticipated sixth season - has admitted he doesn't know in "detail" how the programme will come to a conclusion, and as a result he isn't sure how many more episodes there will be.
Speaking on the Royal Television Society's 'In Conversation With', he said: "Yes, I do know how it will end. As an overview yes, but in terms of detail no.
“We would figure out the number of episodes based on the detail. I am in this very fortunate position where I can do other things and then come back to 'Line Of Duty'.
“The fact is I’m not doing 'LOD' year in, year out and they allow me to explore other ideas. If you have success in a particular genre you will be considered more marketable in that genre.
“Should you play to your strengths or is it you would enjoy doing something fresh?”
Jed also played down the idea of the drama moving from the Beeb to a streaming platform if the broadcaster decided to stop airing it.
He added: "I don't know if [it'd go to Netflix] if it was dropped. I think in the UK there's not really much of a tradition of going from channel to channel.
"It's quite rare for something to be dropped and then picked up by another channel. I think the chances are quite slim.
"If 'Line of Duty' got dropped by the BBC, I don't think it would automatically get picked up by anyone else."
Meanwhile, Adrian Dunbar - who plays Superintendent Ted Hastings on the show - has suggested the sixth series could be the last, with bosses "trying to bring the current storylines to an end".
He told the Belfast Telegraph newspaper: "This series we are trying to bring the current storylines to an end.
"We might go again for a seventh series. I don't know. That's in the lap of the gods."
