A recent challenge to the European Union (EU) created by a member state is migration. Over the past few years, several EU member states have faced difficulties related to the influx of migrants and refugees, leading to tensions within the bloc regarding how to handle migration policies and responsibilities. Countries like Hungary and Poland have taken a hardline stance by refusing to accept asylum seekers under EU quota systems, which has led to disputes over adherence to EU laws and principles.
While issues like free trade, Brexit, and the euro also present challenges, migration has been particularly contentious as it directly affects the EU's cohesion and its fundamental principles of solidarity and free movement.
