Multi-speed Europe

Multi-speed Europe or two-speed Europe (called also "variable geometry Europe" or "Core Europe" depending on the form it would take in practice) is the idea that different parts of the European Union should integrate at different levels and pace depending on the political situation in each individual country. Indeed, multi-speed Europe is currently a reality, with only a subset of EU countries being members of the eurozone and of the Schengen area. Like other forms of differentiated integration such as à la carte and variable geometry, "multi-speed Europe" arguably aims to salvage the "widening and deepening of the European Union" in the face of political opposition.
