The EU accession aspirations of the de jure European country Turkey remain a highly contested issue. Due to the national preferences and mainly socio‐cultural resentment in some EU Member States and due to its limited integration capacity, the EU offered Ankara a discriminatory ‘full membership minus’. The current EU law and the various paradigms of ‘differentiated integration’ do not only provide the spatial, temporal and thematic scope for a conceptual framework on accession alternatives, they also limit it. In this context, the gradual integration/membership concept could be an interesting option for both parties. The depreciation of full membership in the case of Turkey has weakened the EU conditionality policy in general. On the other hand, ‘external’ flexibilization can help to overcome deadlock by allowing the Member States and accession candidates such as Turkey to co‐operate at different levels of integration.
