London, Jan 28: Greece has “seriously neglected” its obligations to control the external frontier of Europe’s passport-free Schengen zone, the European Commission says in a draft report.
The assessment found failures to register, check and fingerprint migrants arriving in November.
Greece is now likely to be given three months to rectify the situation.
If it does not improve, the EU may recommend other Schengen states to reintroduce temporary border controls.
The migrant crisis has put the future of the Schengen agreement at risk.
Several EU states, including Austria and Hungary, have already introduced temporary border controls to reduce the number of arrivals.
Greek ministers have reacted angrily to previous suggestions the country could be isolated from the EU’s free movement principle.
