Directed by Toby Haynes and starring Benedict Cumberbatch, Brexit goes behind the scenes of the United Kingdom's 2016 referendum to leave the European Union, and the data-driven tactics of the "Vote Leave" campaign that brought home a political victory.

Brexit: The Uncivil War follows the campaign from the perspective of the largely unknown strategists in both the leave and remain camps as they plot to gain advantage over each other, while dealing with politicians jostling for the limelight and controversial financial backers.

Benedict Cumberbatch (Sherlock, Doctor Strange, Patrick Melrose) is Dominic Cummings, the lead strategist and Campaign Director of Vote Leave. Rory Kinnear (The Imitation Game, Skyfall) co-stars as Craig Oliver, Prime Minister David Cameron’s Director of Communications, overseeing the Remain campaign’s communications strategy.

At a time when explosive revelations about the mining of personal data and the corrosive effect of fake news and micro-targeted advertising through social media feeds are at the forefront of the news agenda, Brexit explores how modern data-driven campaigning techniques contributed to one of the most unexpected, highly-charged and controversial decisions in modern political history.

Brexit will air in the UK on Channel 4 at 9pm on 7th January 2019.
