The European Commission is set to propose new rules for deporting migrants who enter the bloc illegally, according to three EU diplomats, Politico reports.

Draft guidelines on returns could be “shared” with member countries’ permanent missions as early as February, diplomats told Politico’s Brussels Playbook. The proposal is expected to be a priority for the Commission, reflecting growing pressure from capitals including Rome and Warsaw.

The Commission is currently consulting with EU capitals to determine the specifics of the guidelines, a diplomat said. Immigration regulations are notoriously complex, involving overlapping national, EU and international law.

Some principles are likely to be included in the new guidelines, including setting out rights and obligations for migrants who have exhausted their legal options to stay in the EU and clarifying rules for their deportation to third countries — which could be either their country of origin , or the place where they have spent significant time.

Another possibility being discussed is restricting the freedom of movement of migrants selected for deportation by “ordering” them to “check in” at a migration centre, allowing authorities to track migrants at risk of disappearing, the same diplomat said.

Since the EU adopted its Return Directive in 2008, pressure for more and faster deportations has increased. Europe has noticeably shifted to the right on immigration in recent years both nationally and at EU level, with far-right parties making big “gains” on an anti-immigrant platform and right-wing forces increasingly influence on Brussels.
