After Brexit, the dynamics of political change in Europe experienced a significant transformation. Britain’s decision to leave the European Union (EU) in 2016 not only had an impact on British domestic politics, but also shook up the political map of Europe as a whole. The process and impact of Brexit triggered various reactions from EU member states and influenced policy, ideology and international relations. One of the most obvious impacts is increased political uncertainty across Europe. EU member states are starting to think about how to reform institutional structures and migration policies to prevent the flow of populism and euroscepticism. Italy and France, for example, have seen an increase in the number of political parties adopting anti-EU policies. This creates tensions in relations between countries as well as influencing elections, especially in countries with populations that are highly critical of EU policies. The European Parliament is becoming an increasingly dynamic arena, with more protest factions seeking to push national agendas. Parties such as the Nord League in Italy and Rassemblement National in France recognize the potential of Brexit as an opportunity to appeal to voters who feel alienated by decisions in Brussels. This led to further polarization within parliament, complicating any attempt to reach consensus. On the economic front, Brexit sparked deep discussions about integration and economic coherence in Europe. Countries such as Germany and France are increasingly pushing for a more coordinated fiscal agenda, seeking to prevent a domino effect from Britain’s breakup. Talks about establishing a minimum corporate tax in Europe have become more urgent in response to the uncertainty arising from Brexit. Shifts in the security sector are also a priority issue. With Britain’s exit, European countries will have to reconsider their common defense strategy. Cooperation in the security and military fields, which previously depended on Britain’s commitment, began to be questioned by other member countries. It is hoped that increasing collaboration within NATO and strengthening the European Defense Union can be a solution to this problem. Meanwhile, the EU’s relations with countries outside Europe, especially the US, are facing new challenges. Foreign policy shifts led by the new administration in the United States are forcing Europe to adapt to new geopolitical dynamics. Europe now tends to strengthen cooperation with Asian partners and countries outside the transatlantic in order to strengthen its bargaining position in the global arena. Overall, post-Brexit, the dynamics of political change in Europe are moving in a more fragmentary direction, with many challenges to be faced. Uncertainty, the rise of populism and the need for structural reform are key elements in facing a new, increasingly complex era in European politics.
