Euroscepticism

Euroscepticism is the criticism of the European Union (EU). Some observers also say that the total rejection of the EU is euroscepticism. Euroscepticism should not be confused with Anti-Europeanism, which is the dislike or fear of European culture and/or people.
Eurosceptics says that the European Union weakens the nation state. They also say that the European Union is too bureaucratic (meaning that important decisions are made by officials who aren't elected). In 2016, the countries with the most unfavourable view of the EU were Greece, France, Spain and the United Kingdom.
The rise of right-wing populist parties in Europe have been contributed to their Eurosceptic views. On 23 June 2016, the United Kingdom voted to leave the European Union with 52% voting to leave.
