This paper argues that the (lack of) foreign language skills has contributed to the outcome of the Brexit referendum. Theory suggests that speaking foreign languages reduces perceptions of cultural distance and contributes to the formation of transnational identities. Research also shows a link between language skills and European identity (Kuhn, 2015;Díez Medrano, 2018). Did Britons' relative lack of foreign language skills play a role in the Brexit decision? The data show that those with foreign language skills overwhelmingly voted to remain. But is this a genuine effect, or are foreign languages skills simply a marker of e.g. higher educational attainment which has been found to predict the individual Brexit vote? Using matching methods and data from the referendum wave of the British Election Study, it is possible to estimate the effect of foreign language skills on the referendum vote.The results suggest that a significant effect of foreign language skills remains, even when taking into account various factors such as education, age, gender, income, and region, as well as party preference and personality differences.
