Ultimate TV crime drama Line of Duty has officially been announced as BBC iPlayer’s biggest show of 2021 and we’re not surprised!

The BBC has officially revealed their streaming figures for 2021, and Line of Duty has surpassed all their competition as the most-watched boxset and the most-watched single episode of this year.

Since the sixth series of Line of Duty kicked off in March, its premiere episode has been seen 9.2 million times on the iPlayer and the series as a whole has been streamed an incredible 137 million times throughout the entirety of this year. The show even beat the Olympics coverage!

This isn’t the first record Jed Mercurio's hit crime drama has won, back in May the show officially became the most-watched drama of the 21st century, drawing in an audience of 15.24 million!

A pretty big deal, don’t you think?

The finale of series six, that aired earlier this year where AC-12's Superintendent Ted Hastings, DI Kate Fleming and DS Steve Arnott finally uncovered the identity of the elusive ‘H’, also became the most-watched episode of any drama since modern records began in 2002.

Addressing the show breaking records, Jed said at the time: 'We're honoured and flattered by the viewing figures for #LineofDuty6," he tweeted. "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.'
