Defence and Security after Brexit: Understanding the Possible Implications of the UK's Decision to Leave the EU: Overview Report

This RAND study examines the potential defence and security implications of the United Kingdom's decision to leave the European Union ('Brexit'). Specifically, it seeks to identify those policy areas, strategic concerns or military capabilities that might be most affected, as well as to explore and define the spectrum of possible outcomes in each area. The goal is to help policymakers both inside and outside the UK to understand the key questions provoked by Brexit, and thus to inform how defence and security actors begin to plan for, mitigate and address these uncertainties as the UK begins negotiations to leave the European Union.
