This paper examines the approach taken by the UK to the eurozone crisis. Looking at UK policy and policy making policy from 2010 to 2015, it is informed by new and original primary source material collected by the authors from a programme of interviews with decision makers. The discussion is framed in terms of a critical reflection on theoretical perspectives, including liberal intergovernmentalism (LIG), which is the adopted framework for the EMU Choices project. Drawing on and responding to, but also building on, the recent problematization of the LIG notion of preference formation by Csehi and Puetter (2017) as applied to the Eurocrisis, the paper assesses the factors, influences and processes that shaped the UK government’s approach to the eurozone crisis, and reflects on the implications of the UK for the analytical value of LIG and alternative theoretical perspectives in capturing the processes at work in the formation of national responses to the eurozone crisis.
