Carole Cadwalladr digs into one of the most perplexing events in recent times: the UK's super-close 2016 vote to leave the European Union. Tracking the result to a barrage of misleading Facebook ads targeted at vulnerable Brexit swing voters -- and linking the same players and tactics to the 2016 US presidential election -- Cadwalladr calls out the "gods of Silicon Valley" ...

Despite an agreement by all groups to suspend campaigning in the aftermath of Jo Cox’s death, Arron Banks instructed the social media team at Leave.EU to “boost” an existing sponsored Facebook ad.

The Brexit deadline is hurtling towards us, and citizens across the UK still aren't allowed to know who bankrolls the politicians deciding the country's future.
