The European Parliament approved a major migration policy overhaul Wednesday to increase deportations and permit member states to establish detention centers abroad, a move critics say creates a harsh system that undermines protections for asylum-seekers.

The move underlines the rise in anti-immigration sentiment across the European Union over ​the past decade that has broadened popular support for far-right ​parties.

The ⁠text, which requires final formal approval from the 27 EU member governments, marks a sharp hardening of EU migration policy that has taken shape since an influx of over a million refugees and migrants in 2015-16.

"The Return Regulation will provide the necessary tools to make returns more efficient, with faster and more effective procedures," European Commission President Ursula von der Leyen said in a letter Tuesday addressed to member states ahead of a meeting of EU leaders in Brussels.

EU countries say they struggle to ensure that rejected asylum-seekers and people who overstay their visas ⁠leave ⁠their territory.
