The Russia-linked troll farm that used Facebook to target Americans during last year's election was also active in the UK ahead of the Brexit vote (Editor's note: the link may be paywalled; alternative source), the social media company has admitted. From a report: In a letter to the Electoral Commission, Facebook said accounts associated with the Internet Research Agency spent $0.97 for three ads in the days before the EU referendum. These ads appeared on approximately 200 news feeds in the UK before the country voted to leave the EU last year. For months the social media company has sidestepped questions from MPs and journalists about Russian interference through its platform in the UK. The concerns were fuelled by revelations this summer that Facebook had been weaponised by Russian entities before the election of US President Donald Trump. France and Germany have said their elections were also targeted. "We strongly support the Commission's efforts to regulate and enforce political campaign finance rules in the United Kingdom, and we take the Commission's request very seriously," Facebook said in the letter.
