A number of factors explain why some EU member states, particularly France, Italy and Spain are gradually opting for informal patterns of cooperation on readmission issues with Mediterranean and African countries. This adaptive inclination is more of a necessity than an option. It reflects the more urgent need of some EU member states to find flexible solutions for cooperation on readmission rather than to conclude bilateral readmission agreements. The agenda remains unchanged, but there has been a shift in priority actions with regard to these countries. The operability of cooperation on readmission has been prioritised over formalisation.
