The right of EU member states to leave the European Union became a live political question after Britain's 2016 Brexit referendum, which exposed deep divisions over sovereignty and integration. The EU's founding treaties contain no explicit exit mechanism, though Article 50 (added in 2009) now permits withdrawal under negotiated terms. Today, this debate reflects broader tensions between national autonomy and collective European governance, with some states questioning whether EU membership serves their interests while others argue exit would be economically and politically costly.
