Fans will be happy to learn that Line of Duty is returning in March.

The BBC has confirmed that the highly anticipated sixth season of the police drama will return to BBC One on Sunday 21 March at 9pm.

The start date was revealed on Saturday (27 February) after a teaser for the show played during the Six Nations match.

Filming on the BBC’s hit police corruption drama had suffered delays as a result of the coronavirus pandemic, amid a spate of postponements and cancellations across the wider film and TV industries.

Earlier this month, it was announced that Line of Duty fans would be getting one additional episode than was originally commissioned. Season six will comprise seven episodes.


A press release stated: “AC-12’s [the name of the show’s fictional anti-corruption unit] highest priority will always be capturing bent coppers.

Kelly Macdonald is also set to feature as the show’s latest guest star, playing Detective Chief Inspector Joanne Davidson, the senior investigating officer on an unsolved murder case whose onduct attracts the attention of Anti-Corruption.

Details of the plot – which creator Jed Mercurio previously called “ludicrously implausible” – have been kept under wraps.

The cast have been busy sharing behind-the-scenes photos ahead of the show’s return.

It is not yet known whether season six will be Line of Duty’s final series, however, Dunbar has previously stated that he believes it will go on “as long as there’s an appetite from our audience for the show”.

“Why should we stop?” said the actor during an appearance on the Graham Norton Radio Show in January.

“We’ve managed to keep the standard, Jed [Mercurio] rather, has managed to keep the standard so high for so long, and people love the show. I hope it does go on.”
