Euroscepticism, also spelled as Euroskepticism or EU-scepticism, is a political position involving criticism of the European Union (EU) and European integration. It ranges from those who oppose some EU institutions and policies and seek reform (Eurorealism, Eurocritical, or soft Euroscepticism), to those who oppose EU membership and see the EU as unreformable (anti-European Unionism, anti-EUism, or hard Euroscepticism). The opposite of Euroscepticism is known as pro-Europeanism.
The main drivers of Euroscepticism have been beliefs that integration undermines national sovereignty and the nation state, that the EU is elitist and lacks democratic legitimacy and transparency, that it is too bureaucratic and wasteful, that it encourages high levels of immigration, or perceptions that it is a neoliberal organisation serving the big business elite at the expense of the working class, that it is responsible for austerity, and drives privatization.
