Abstract This article examines the complex relationship between neoliberalism and the Brexit campaign. It proposes to move beyond simplified explanations that see in Brexit a ‘populist’ revolt against the neoliberal status quo by drawing attention to neoliberal ideas surrounding Europe and the free market. The article contends that from the 1990s onwards, many prominent neoliberal thinkers came to see the European Union as a threat to free trade and individual liberty, prompting them to support Brexit as a means of subverting the growing influence of European federalism. In building this argument, the article maps and analyses the key theoretical elements of neoliberal Euroscepticism, focusing in turn on the neoliberals’ interpretation of the European project, their critique of European Monetary Union, and their approach to the question of national sovereignty. It then documents how several neoliberal think tanks came increasingly to support and spread this neoliberal form of Euroscepticism. In closing the article reflects on the influence of neoliberal Euroscepticism on the current Conservative government.
