Russian interference in the 2016 Brexit referendum

Russian interference in the 2016 United Kingdom European Union membership referendum is a debated subject and remains unproven, though multiple sources argue evidence exists demonstrating that the Russian government attempted to influence British public opinion in favour of leaving the European Union. Investigations into this subject have been undertaken by the UK Electoral Commission, the UK Parliament's Culture Select Committee and Intelligence and Security Committee, and the United States Senate.
