Enlargement of the European Union was one of the priorities outlined by Commission President Ursula von der Leyen in her State of the Union speech on September 13th, and it is likely to become an ever more pressing issue over the next few years. After the speech, Talking Europe sat down with the EU Commissioner in charge of neighbourhood and enlargement, Olivér Várhelyi. He is a distinguished Hungarian diplomat and lawyer. He served as Hungary's ambassador to the EU, and has held prominent positions at the Hungarian ministry of justice and ministry of foreign affairs.
