"The possibility that both Brexit and the Trump campaign simultaneously relied upon the same social-media company and its transgressive tactics, as well as some of the same advisers, to further far-right nationalist campaigns, set off alarm bells on both sides of the Atlantic. Damian Collins, a member of Parliament, and chair of its Digital, Culture, Media and Sport Committee, which held an inquiry into fake news, told the Observer, which has broken much of the news about Cambridge Analytica in the U.K., that the new e-mails “suggest that the role of Bannon and Mercer is far deeper and more complex than we realised. There’s a big question about whether Mercer’s money was used in the Brexit campaign and it absolutely underscores why Britain needs a proper Mueller-style investigation. There are direct links between the political movements behind Brexit and Trump. We’ve got to recognise the bigger picture here. This is being coordinated across national borders by very wealthy people in a way we haven’t seen before."New Evidence Emerges of Steve Bannon and Cambridge Analytica’s Role in Brexit | The New Yorker
The American investigations into foreign interference in Trump’s election, and British probes into Brexit, have increasingly become interwoven. The role of the Russian Ambassador to the U.K., Alexander Yakovenko, has reportedly been the subject of interest both to Mueller’s investigators and to those in the U.K., who have examined his relationship to Banks. The role of Nigel Farage, the former leader of the far-right, Euroskeptic U.K. Independence Party, who has been an ally of Bannon and Trump, has also reportedly stirred the interest of investigators in both countries, especially after he was spotted in 2017 leaving the Ecuadorian Embassy in London, in which Julian Assange has taken refuge. Assange’s media platform, WikiLeaks, published many of the e-mails stolen by Russia from the Hillary Clinton campaign during the 2016 election season."
