Turkey's relations with the EU have seriously deteriorated in the aftermath of the 2016 Turkish coup d'état attempt and subsequent purges. 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. 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", as Turkey's path toward autocratic rule made progress on EU accession impossible. As of 2017, and especially following Erdoğan's victory in the constitutional referendum, Turkish accession talks are effectively at a standstill.
