United Kingdom (UK) is the first state to withdraw its membership in the European Union (EU). This historic moment is also commonly known as Brexit, an abbreviation of the words Britain and exit, referred to the scenario of potential Greece withdrawal from the eurozone following Greece debt crisis. Brexit caused the pound sterling to plummet against other major currencies and David Cameron’s swift resignation from his position as prime minister. It also triggers a possibility of second Scottish referendum and possibility for Northern Ireland’s reunification with the Republic of Ireland. However, it is still unclear whether UK’s withdrawal will result in peaceful and close ties with EU with reform in many areas or a violent severance of relations between UK and EU.
