With formal accession talks between Turkey and the European Union beginning in the years 2004 and 2005, the role of Chief Negotiator was established to represent the Turkish delegation during the membership negotiations. Prime Minister Recep Tayyip Erdoğan appointed Ali Babacan as the first Chief Negotiator on 17 January 2005, while the then-Foreign Minister Abdullah Gül became the president of the Turkish delegation.[1]
When the Ministry of European Union Affairs was established on 29 June 2011 before Erdoğan formed his third and final government, the Minister responsible for the new department began serving concurrently as the Chief Negotiator. The only event in which this was not the case occurred between 28 August and 22 September 2015, where Ali Haydar Konca was appointed as the Minister for European Union Affairs but was not, according to official records, appointed as the Chief Negotiator.[2]
