Résumé:
The issue of the withdrawal of the United Kingdom from the European Union is one of the
most important issues in the history of Britain in particular, and in Europe in general. The
European Union received the news of the Brexit with all the sorrow and concern about its fate in the future, especially that Britain was considered as an important member within it. The Union shall provide facilities to enable each State or Member to act absolutely free, such as freedom of movement without obstacles and the freedom to market products. Since the British economy is more developed than other countries. So Britain did not see joining the Union as an advantage, which will bring UK out from darkness to light, on the contrary, it sees itself losing many of her relations with super powers such as America and China, which the Union's laws do not allow it to make a partnership with them. This factor and other factors made Britain choose another way. So this modest project includes the most important reasons and results, which was witnessed by Britain before and after the decision of the withdrawal.
More importantly, this study examines the effect of exiting on the Union, and the future of the European Union threatened with disintegration, especially there are many countries
demanding leaving the European integration.
