Report: The regulation of campaigners at the referendum on the UK’s membership of the European Union held on 23 June 2016

About the referendum

Our first report on the EU referendum, published in September 20161 , focused on the administration of the referendum, including the experience of voters and campaigners, the management and delivery of the poll, the regulation of campaigners at the referendum and the provision of information for voters.

This second report includes information on the use of our investigatory and sanctioning powers and analyses the funding and spending of those people and organisations that registered to campaign. Where appropriate, we make recommendations to inform the regulation of future referendums based on the information campaigners were required to submit in their spending and donation returns2 .
