OnlyFans: Inside the Machine

9pm, BBC Three
A beacon of sexual liberation and entrepreneurship or a giant exploitation machine? As more and more money is made through adult content on OnlyFans, agencies that offer to manage creators’ careers have begun to cash in. Some do their jobs and help businesses to expand.

Brexit: A Very British Civil War

9pm, BBC Two
The second and concluding episode of a documentary that has illustrated so many of the flaws of recent British political reporting: most notably the preference for drama and personalities over policy discussion.

G’wed

10.35pm, ITV2
The raucous scouse sitcom goes full bed-hopping sex farce at a swanky country club hotel.

Film choice

The Power of the Dog (Jane Campion, 2021) 12.05am, BBC Two

Jane Campion’s sensuous, psychosexual western explores the unspoken emotions that can sway people’s actions. Benedict Cumberbatch (cast fruitfully against type) and Jesse Plemons play ranching brothers in 1920s Montana – charismatic alpha male Phil and taciturn, decent George. After George brings home new bride Rose (Kirsten Dunst) and her teenage son Peter (Kodi Smit-McPhee), Phil’s jealousy ebbs as he mentors the kid in the ways of the cowboy. An undercurrent of homoerotic tension runs through a deep, dark tale. Simon Wardell
