Brexit: mocenské postavení Velké Británie po odchodu z EU

In international relations, rationally acting states pursue the acquisition and further preservation of power that characterises their power status. The process of Britain leaving the EU is not an exemption as it represents an interest to strengthen Britain’s national power. The main goal of this thesis is to identify changes in the power status on a case study of Great Britain during the Brexit process on the basis of analysing primary sources and secondary documents that deal with the Brexit question and status of Great Britain in the international sphere. As the term of power is traditionally linked to the realistic theory of international relations, the secondary goal of the thesis is to evaluate the changes of power status from the perspective of classical realism. From the conclusions, we can find out that Britain’s power status in individual dimensions of power has not changed based on analysed trends, and thus Brexit has not significantly influenced British political power. Consequently, new challenges and opportunities are opening for Britain in forming its continuous power status on both European and international scenes.
