The move escalates the domestic political debate surrounding migration policy to the European level, placing the Spanish government’s approach under scrutiny by EU institutions. Background to the regularisation proposalThe regularisation plan is linked to a popular legislative initiative currently being processed in the Spanish Parliament. Ministers have said that regularisation would improve legal certainty, strengthen labour protections and help bring economic activity into the formal system. European policy frameworkEU law does not explicitly prohibit member states from carrying out national regularisation processes.
