The Guardian reports:
The US billionaire who helped bankroll Donald Trump’s campaign for the presidency played a key role in the campaign for Britain to leave the EU, the Observer has learned. It has emerged that Robert Mercer, a hedge-fund billionaire, who helped to finance the Trump campaign and who was revealed this weekend as one of the owners of the rightwing Breitbart News Network, is a long-time friend of Nigel Farage. He directed his data analytics firm to provide expert advice to the Leave campaign on how to target swing voters via Facebook – a donation of services that was not declared to the electoral commission.
Cambridge Analytica, an offshoot of a British company, SCL Group, which has 25 years’ experience in military disinformation campaigns and “election management”, claims to use cutting-edge technology to build intimate psychometric profiles of voters to find and target their emotional triggers. Trump’s team paid the firm more than $6m (£4.8m) to target swing voters, and it has now emerged that Mercer also introduced the firm – in which he has a major stake – to Farage.
The communications director of Leave.eu, Andy Wigmore, told the Observer that the longstanding friendship between Nigel Farage and the Mercer family led Mercer to offer his help – free – to the Brexit campaign because of their shared goals. Wigmore said that he introduced Farage and Leave.eu to Cambridge Analytica: “They were happy to help. Because Nigel is a good friend of the Mercers. And Mercer introduced them to us. He said, ‘Here’s this company we think may be useful to you’. What they were trying to do in the US and what we were trying to do had massive parallels. We shared a lot of information.”
