With MPs poised to make the most momentous decision in recent British history, this new documentary in ITV's award-winning Exposure strand investigates the new, inflammatory, unregulated world of online political campaigning. Over the last 12 months, Exposure has had exclusive access to MPs and Lords who have experienced a barrage of menacing messages and even death threats on social media because of their views on Brexit, and searches for those who abuse and intimidate online. The programme also questions the impact that divisive and aggressive digital campaigning is having on our democracy.
