, accession negotiations are under way with Albania (since 2020), Montenegro (since 2012), North Macedonia (since 2020), Serbia (since 2014) and Turkey (since 2005). Serbia and Montenegro have been described by former President of the European Commission Jean-Claude Juncker and Enlargement commissioner Johannes Hahn as the frontrunner candidates, and projected that they would join by 2025, during the next mandate of the European Commission.
