This Article analyses recent developments in Union citizenship, in particular the relationship between Articles 20 and 21 TFEU. In doing so, it divides Union citizenship into a transnational and a supranational dimension with the transnational dimension having two sub-dimensions: social integration and autonomy. It is argued that we are seeing an increased emphasis on the responsibility of the individual citizen in the context of the transnational dimension and a clear linkage between the transnational and supranational dimensions. The result of these two moves is a status which continues to emphasise the relationship between the Union citizen and the communities represented by Member States, while framing this with a more prominent supranational dimension.
