Turkey's president says an upcoming vote in the European Parliament on whether to freeze membership talks with Turkey is of no "value" to his country.

European Union legislators are scheduled to hold a non-binding vote this week on whether Turkey's accession talks should be suspended over the Turkish government's unprecedented crackdown following the failed military coup in July.

Addressing an Organization for Islamic Cooperation Islamic Conference meeting on Wednesday, Recep Tayyip Erdogan said: "Whatever the result is, in our eyes this vote has no value."

EU nations have voiced concern over Turkey's post-coup clampdown, which has resulted in mass purges, the arrests of journalists and politicians and the closure of media outlets.

Erdogan suggested joining the Shanghai Cooperation Organization, which includes Russia and China, as an alternative to the EU.
