Line Of Duty was iPlayer's most popular show in what looks set to be a record-breaking year for the service, the BBC has revealed.
The Jed Mercurio drama - renowned for its twists and turns - returned for its sixth series in March and the latest iPlayer figures show that the first episode has since been streamed an incredible 9.2 million times on iPlayer.
The streaming service has all six series available and in total, there have been 137 million streams of episodes of the show across the year to date.
Also performing well in 2021 were submarine-set thriller Vigil, with 8 million streams of episode one; the Olympics, with 90.2 million streams across the fortnight of action; and Euro 2020, which generated 68.2 million streams, including 6 million for the final between England and Italy.
Dan McGolpin, director of iPlayer, said: "It's been an incredible year for BBC iPlayer with a unique mix of programmes driving more viewing than ever before.
"Line of Duty tops the tables and it's fantastic to see so many other brand-new drama series also featuring highly alongside those memorable sporting moments from last summer and some of the best documentary series of the year.
"Of course the year's not over yet and BBC iPlayer has something for everyone this Christmas, brand new boxsets like The Girl Before, A Very British Scandal and Around the World in 80 Days, a thrilling selection of blockbuster movies and an unrivalled collection of Christmas specials both past and present."
