International legal effects of the withdrawal of Great Britain from Europe Union

The United Kingdom (UK) is a member in the European Union (EU) that has never had strong ties with the EU and its national interests has always been preferred over the EU. The latest example of the lack of understanding between EU and UK is visible in 2016 by secession referendum. The UK's secession referendum has pros and cons that voices of dissent were strong heard. However, this referendum is not all the way and UK for withdraing from the EU must start Article 50 Lisbon mechanism’s in accordance with the constitution of Britain. If the UK withdraw from EU, this separation will costly for UK and EU but we must consider the fact that whatever is disagreement between the parties, there are some minimum and common points that can keep UK in the EU.
