By bundling the manifold policy expertise of the researchers of the Institute for European Studies (IES), this paper forms part of a series of analyses investigating the potential implications of a ‘Brexit’ scenario for different EU policies. All papers ask the same three questions: 1) What is the state of the EU policy in focus? 2) What is the UK’s role/interest in this policy field? 3) What are the potential implications of a ‘Brexit’ scenario at the policy-level?
