Abstract

We assess the impact of the United Kingdom’s 2016 decision to leave the European Union on the Council of the European Union, where Brexit is likely to have the clearest observable implications. Using concepts and models from the spatial model of politics and network analysis, we formulate and test expectations regarding the effects of Brexit. We examine two of the most prominent datasets on recent decision-making in the European Union, which include data on cooperation networks among member states before and after the 2016 referendum. Our findings identify some of the political challenges that Brexit will bring, but also highlight the factors that are already helping the European Union’s remaining member states to adapt to Brexit.
