Did Terrorism Affect Voting in the Brexit Referendum?

This article contributes to the recent research on Brexit and public opinion formation by contending that the determinants of the referendum results should be evaluated against the background of wider public security concerns. The British public has long regarded terrorism as a top concern, more so than in any other European country. Terrorist attacks on UK soil raised voters' awareness of security issues and their saliency in the context of the EU referendum. The study finds that locations affected by terrorist violence in their proximity exhibit an increase in the share of pro-Remain votes, particularly those that experienced more sensational attacks. Using individual-level data, the results show that in the aftermath of terrorist attacks, citizens are more likely to reconsider the security risks involved in leaving the EU.
