Europe’s migration divide deepens over national sovereignty and border controls.
BRUSSELS
Denmark has called on the European Commission to examine Spain’s plan to regularize the status of approximately 600,000 undocumented migrants, intensifying a political dispute over immigration policy and the responsibilities of European Union member states.
Danish Prime Minister Mette Frederiksen raised the issue during an EU summit in Brussels, questioning whether large-scale legalization measures are compatible with the increasingly restrictive migration policies supported by several European governments.
Her intervention places Denmark and Spain on opposing sides of a debate extending beyond traditional political divisions. Although Frederiksen and Spanish Prime Minister Pedro Sánchez belong to Europe’s broader social democratic political family, their approaches to immigration differ substantially.
Frederiksen maintains that granting legal status to undocumented migrants could encourage additional irregular arrivals. Her concerns reflect the position of governments seeking stronger external border enforcement, faster returns and tighter conditions for residency.
Sánchez, meanwhile, has defended Spain’s regularization approach as part of a broader strategy combining economic integration, human rights and migration management. His government argues that legal recognition can help bring undocumented workers into the formal economy while improving access to employment protections and public administration.
The controversy also exposes a structural tension within the European Union. Although member states retain significant authority over residence permits and national migration procedures, decisions affecting hundreds of thousands of migrants can raise questions about mobility and coordination within the Schengen area.
The number of people potentially affected has become another element of the discussion. Earlier estimates associated with Spain’s initiative referred to approximately 500,000 migrants, while the current European debate has focused on a figure approaching 600,000. These estimates should not be confused with the number of residence permits ultimately granted.
Denmark has also supported initiatives involving reception and return arrangements outside EU territory, alongside countries including Germany, Austria, Greece and the Netherlands. These proposals form part of wider efforts to reshape European migration management.
The political disagreement comes as European institutions continue implementing the Migration and Asylum Pact, which seeks to strengthen common procedures while addressing differences among national governments.
The central question is whether national regularization initiatives can coexist with increasingly coordinated European border policies. Assessing their consequences requires evidence about migration movements, labor markets and administrative outcomes rather than assuming that either legalization or restriction produces a predetermined result.
For Brussels, the dispute illustrates the continuing difficulty of developing a common migration strategy across governments with different economic needs, domestic political pressures and interpretations of European solidarity.
As EU leaders negotiate their next steps, the debate over Spain’s initiative is becoming a broader examination of how national sovereignty operates within a shared European migration framework.
