The development of European integration has meant that member states have experienced Europeanization and as a consequence the EU has become a more politicized issue in domestic politics. This has come over time and as a consequence of the decline of a permissive consensus. This has been manifest in the growth of political parties expressing Euroscepticism but there is great variety in the types of parties expressing this and in the sorts of issues that Euroscepticism is mobilized around in different member states.
