Former Brexit negotiator Michel Barnier has cautioned that electoral victories for nationalist or populist parties in France and Germany would threaten the future of the European Union. In an interview with Le Figaro, Barnier stated the Brexit referendum served as a warning to heed popular concerns. He believes ignoring these anxieties could lead to further disintegration within the bloc. Barnier, who previously served as a French minister, emphasized the potential consequences of a shift towards nationalist ideologies in key member states. He suggested that such a development would effectively dismantle the existing European project. The comments come amid rising support for far-right parties across Europe, particularly in the lead-up to upcoming elections. Barnier’s remarks underscore the fragility of European unity and the importance of addressing public discontent.
