The 2017 European Chronicles open with a brief summary of the major political, economic and institutional events of the year, such as the beginning of the Brexit procedure (the United Kingdom’s withdrawal from the European Union). The Chronicles then analyse the main developments of the European integration process, through the conclusions adopted by the meetings of the European Council, as well through the main EU legislative acts and actions. The Chronicles then provide a synthesis of the most important institutional and legal news, the relationships between citizens and EU institutions, and the main evolutions that occurred in the context of the economic and monetary union. The central part of the text presents the noteworthy developments that took place in 2017 in the context of the regulatory functions (internal market, electronic communications, competition, State aid, social policy, health and consumer protection, environmental protection) and of the distributive functions (common agriculture policy, research and technology, education and culture), as well as the EU’s financial programming and budget. The 2017 European Chronicles close with an analysis of the developments that unfolded in the area of freedom, security and justice, in the external relations of the EU and in the field of the common foreign and security policy.
