There is no doubt that season six was the most successful to date for the BBC crime drama.

Season six, episode one saw 9.6 million viewers tune in - half a million viewers more than the finale of season five.

Since then, the show has continued to rack up more viewers each week, with each episode reaching 15 million viewers when including catch-up and on demand viewers.

The penultimate show, which aired on 25 April, brought in 11 million viewers in the evening on which it was shown Live, according to the BBC.

The episode pipped director Jed Mercurio’s other BBC thriller ‘Bodyguard’ to the post, which reached an overnight peak of 10.4 million viewers for the finale in 2018.

It launched Line of Duty into record-breaking territory, as the most watched drama since the 2008 Doctor Who Christmas Special, which was watched by 11.7million viewers live.

Prior to the finale, 15.2 million viewers on average tuned in to watch each episode of series six when including on-demand views.

How big was the audience for the finale of season 6?

The final episode of Line of Duty season six was the BBC show's most-watched episode to date, averaging 12.8 million viewers on the first night.

This number is expected to grow as on-demand views rack up.

This makes episode seven the UK’s most watched drama in two decades. The last time overnight ratings were higher was during an episode of Heartbeat in February 2001, which had an overnight audience of 13.2 million.

The show has also now surpassed Doctor Who's 2008 Christmas special, commanding 56.2% of the UK's TV audience, according to overnight figures.

The BBC explained how overnight viewing figures had become somewhat irrelevant due to the growth of on-demand viewing, but Line of Duty seems to have kicked the trend, with four million watching live and the other eight million viewing overnight.

**Spoiler alert - season six finale details below**

In the record-breaking finale of season six, the identity of criminal mastermind ‘H’ was revealed as Detective Superintendent Ian Buckells (Nigel Boyle).
