The aim of the study is to examine which part of agricultural and food trade between Visegrad countries and the United Kingdom is threatened by Brexit. On 23 June 2016, the United Kingdom voted in a referendum to leave the European Union, but this has not yet taken place, though it should have happened by 29 March 2019. Therefore, it remains uncertain and the conditions the exit remain to be seen. In the absence of a final agreement, it is only possible to determine currently competitive sectors that could remain in this situation in the future, too. Competitiveness studies can provide guidance to determine expected effects. For products with a lower competitiveness value, turnover is expected to decrease due to changing regulations or increasing duties. Based on the long-term analysis of agri-food trade values of the parties, it is clear that markets are sufficiently diversified. So British withdrawal will not result in significant consequences in the case of Visegrad countries. In terms of trade relations, highly processed products are expected to be competitive in the future.
