Abstract
The date 23 June 2016 brought in front of the United Kingdom and the European Union a very serious challenge named Brexit. In the June 23, 2016 referendum, the British voted to leave one of the most unique international organizations in the world, thus putting the EU in front of the UK’s request for the activation of Article 50 of the Lisbon Treaty, which the EU is facing for the first time. Brexit is opening new chapters in the history of the UK, while the EU is engaging with the procedures of the voluntary withdrawal of an important member state, which is known about its high political and military role in the world. Some experts of international relations and European studies say that Brexit will have much more consequences for the UK, some for the EU, but truth is that Brexit will be accompanied with many consequences for both of its protagonists. Its risks are very serious so they may result with the dissolution of the UK. Meanwhile, the increase of euroscepticism within the EU’s member states, with particular emphasis the presence of Eurosceptic voices in its most important members is at a very worrying level. Based on these facts, the knowledge about the real meaning of Brexit is necessary. Therefore, the main focus of this research lies in the classification of the main political consequences of Brexit for the UK and the EU.
