The functioning of the union of countries with various political, economic, social, and cultural orientations is an important question, which lies in the feasibility of such a union. The United Kingdom is one of the countries that had a peculiar national development strategy that became inconsistent with the pan-European direction. Resolving the problems that have arisen within the framework of cooperation between the UK and the European Union is important to ensure the continued future existence of the EU and to maintain stability in Europe as a whole. The disadvantages and problems that resulted from Brexit could have a major impact on the EU, as the UK was one of the largest and most influential members of the EU. The purpose of this study was to examine the consequences of Britainʼs withdrawal from the EU for Ukraine and Europe as a whole. It is also possible to explore potential opportunities for further development of relations between Ukraine and the UK, given the new conditions after the UKʼs exit from the EU. The study used such scientific methods as chronological, comparative, and historical, systematisation, analysis and synthesis, generalisation, and graphical. The main results of the study of the topic are to determine the history of Britainʼs existence in the European Union, to substantiate the specific features of political behaviour in the Union, to identify the reasons and factors that influenced the countryʼs withdrawal from the European Union. One of the tasks was to investigate the direction of the UKʼs international strategy towards Ukraine. The study analysed the development of Ukrainian-British relations in the late 20th and early 21st centuries. The paper described the consequences of Britainʼs withdrawal for Europe and Ukraine. The study showed the directions of Britainʼs foreign policy towards Ukraine in 1992-2016. The problems and prospects of Ukrainian-British relations after Britainʼs withdrawal from the European Union were considered. This study can help communications professionals understand how to communicate Brexit to the general public in Ukraine and Europe. The study can also help in understanding how to interact with British colleagues working in the field of international relations and trade
