Warning: spoilers for the series six finale of Line of Duty.

Don’t say we didn’t warn you!

The series that everyone has been talking about came to an end this weekend. It was the finale of Season 6 of Line Of Duty.

However, it wasn’t all everyone was hoping for. Soon, the word “disappointing” was trending on Twitter.

On Sunday night the long-awaited secret was revealed: former Detective Superintendent Buckells was the corrupt police officer otherwise known as ‘H’.

He was referred to by AC-12 boss Superintendent Ted Hastings as ‘The Fourth Man’.

Now fans are making their own conspiracy theories.


Plenty of them believe that Buckells (played by Nigel Boyle) may have been based on Boris Johnson.

Former Labour Party spokesperson Alastair Campbell even joined in with the speculation.

Many viewers were disappointed, as they had believed that Buckells was just rubbish at his job.

However, the finale saw him confess to working with the Organised Crime Group (OCG).

The tweets linking Buckells to Boris were retweeted by World Productions, the company that makes the series.

Social Media

One of the popular tweets features a transcript of the final speech made by Hastings.

However, they’ve crossed out ‘Ian Buckells’ and written ‘Johnson’.

The word ‘officer’ was replaced by ‘politician’ in a sentence that originally read: ‘Ian Buckells was an incompetent officer.’

‘I wonder if the reason so many people are angry, is because they don’t want to acknowledge that this guy is basically Buckells?’ one person tweeted with regards to the reaction to the series six finale.

‘Incompetent men being promoted to a level of power and corruption…. hmm sounds familiar @BorisJohnson,’ someone else wrote.

Another Twitter user shared a picture of Buckells alongside a picture of the prime minister with his hand over his mouth, writing the quote: ‘Your corruption has been mistaken for incompetence.’

‘”I just pass things on.”Big Boris vibes tonight from @jed_mercurio,’ someone else remarked.

Alastair Campbell

Alastair Campbell was recently announced as the new guest presenter on Good Morning Britain. He tweeted: ‘“How some people can fail upwards beggars belief” – the best @jed_mercurio troll of @BorisJohnson yet #LineOfDuty.’

Actor Nigel appeared on BBC Breakfast, and he said above all, fans of the show are “brilliant”.

“There’s always going to be some element of disappointment. You can’t have every series with a big shoot out and “urgent exit required”. Sometimes a subtler message is more important,” he said.

Jed Mercurio, the creator of the show, admitted that the final instalment “wouldn’t appeal to everyone”.

He wrote: “We’re honoured and flattered by the viewing figures for #LineofDuty6. We knew attempting to explore the real nature of corruption in our society wouldn’t appeal to everyone, but we do sincerely thank you all for watching,”

“It’s been our privilege to share your Sunday nights.”

However, it’s not known if there will be a seventh series.


Jed told Craig Parkinson during an episode of Obsessed With… Line of Duty on BBC Sounds: “I suppose it was really down to the decision to kind of hold him to account mid season. There were suspicions around him in the first few episodes, AC-12 get him in and they charge him, off he goes to prison and it feels like he’s done and dusted.”

“And I think that if we kept him as part of the action all the way through, then it would have been very hard to misdirect the audience, so we were trying to present other candidates to take the kind of focus away from him.”

Finally, he concluded: “But it was always really important to me that it was someone who’d been in season one – someone who’d been there the whole time.”

“It was really about the heritage of the series, going all the way back to season one, where Dot Cotton says, ‘Oh, can I just have a quick word’ with Tommy Hunter in the back of the van.”

Record Breaker

An incredible 12.8 million viewers watched the final episode.

So were you disappointed with the ending?
