The single biggest known British political advertiser on Facebook is a mysterious pro-Brexit campaign group pushing for a no-deal exit from the EU. The revelation about Britain’s Future, which has never disclosed the source of its funding or organisational structure, has raised concerns about the influence of “dark money” in British politics.

The little-known campaign group has spent more than £340,000 on Facebook adverts backing a hard Brexit since the social network began publishing lists of political advertisers last October, making it a bigger spender than every UK political party and the government combined.
...
The sophisticated campaign includes thousands of individual pro-Brexit adverts, targeted at voters in the constituencies of selected MPs. The adverts urge voters to email their local representative and create the impression of a grassroots uprising for a no-deal Brexit. The MPs then receive emails, signed by a “concerned constituent”, demanding a hard Brexit. The emails do not mention the involvement of an organised campaign group.

Britain’s Future’s public presence contains links to just two individuals: an ex-BBC Three sitcom writer turned journalist, and, indirectly, a former BNP candidate who lives on a farm called Rorke’s Drift in the Yorkshire dales.
