The sixth series of Line of Duty was a huge success.
According to the BBC, which shows the police drama written by Jed Mercurio, the penultimate episode alone drew an average of 11 million viewers and more than half of the audience.
Demand for a seventh series of the show, following the activities of the AC-12 anti-corruption division, was fierce, and fans asked the producers to continue the story.
A Twitter user summed up the mood on Sunday with the words: “Please let it be a Series 7 so I can look forward to something.”
Mercurio was careful and told the Radio Times: “We are in a situation where it is not entirely clear that there will be a seventh series.
“We’d hope there could be. But we have to do our planning out of Covid and a whole host of other things to materialize the idea that these things are currently not guaranteed at all.”
He added, “We’ve been talking to the BBC about the realistic longevity of the show since probably season four. I saw broadcasters pull the plug while we were still developing a storyline.
“So it’s an ongoing discussion, that’s all I can say. A lot depends on whether the main creatives – me and the main characters – find new stories to tell in this universe.”
In the finale of the sixth series, which was shown on BBC One on Sunday evening, hopes for the search for “H” – a corrupt police officer responsible for a mass conspiracy – came to an end.
There have been many theories about her identity – a YouGov poll earlier this week found that viewers of the program thought Chief Constable Philip Osborne was the most likely candidate for H.
But in the last episode of the sixth series, DSI Ian Buckells was grilled about whether he was “H”, to which he replied, “I’m just the one who made a lot of cups out of you.”
The closing scenes included subtitles that summarize the story in its current form, showing Buckells being locked up in a cell.
There was also a suggestion that evidence related to institutionalized corruption may not be able to be tried in court.
Footage of pictures of police officers being removed from a wall in the station were final – but whether this was the final episode has not been confirmed.
Kate Fleming – the character of Vicky McClure – heard her say, “You don’t know what you have until it’s gone,” commenting that someone was still needed to keep everyone informed.
Maybe Mercurio can find a new angle for another series after all …
