Yet forty years after the first enlargement, which saw the UK join the European Community, confidence in the European project seems to be at an all-time low. From enlargement fatigue within the EU to Russian overtures to Eastern European states and the fading prospects of Turkish accession, enlargement faces daunting challenges. In the context of the ongoing economic and political crises in the EU, we may well ask: Is EU Enlargement in crisis?
