Turkey's relations with the EU have seriously deteriorated in the aftermath of the 2016 Turkish coup d'état attempt and subsequent purges.[25][26] On 24 November 2016 the European Parliament approved a non-binding resolution calling for the "temporary freeze of the ongoing accession negotiations with Turkey" over human rights and rule of law concerns.[27][28][29] On 13 December, the European Council (comprising the heads of state or government of the member states) resolved that it would open no new areas in Turkey's membership talks in the "prevailing circumstances",[30] as Turkey's path toward autocratic rule made progress on EU accession impossible.[31] As of 2017, and especially following Erdoğan's victory in the constitutional referendum, Turkish accession talks are effectively at a standstill.[4][32][33]
