Turkish President Tayyip Erdogan says a vote by the European Parliament on whether to halt EU membership talks with Ankara "has no value in our eyes" and again accused Europe of siding with terrorist organisations.
"We have made clear time and time again that we take care of European values more than many EU countries, but we could not see concrete support from Western friends ... None of the promises were kept," he told an Organisation of Islamic Co-operation conference in Istanbul.
"There will be a meeting at the European Parliament tomorrow, and they will vote on EU talks with Turkey whatever the result, this vote has no value in our eyes."
Leading members of the European Parliament on Tuesday called for a halt to EU membership talks with Turkey because of its broad purges following a failed July coup.
More than 125,000 people - including soldiers, academics, judges, journalists and Kurdish leaders - have been detained or dismissed over their alleged backing for the putsch, in what opponents, rights groups and some Western allies say is an attempt to crush all dissent.
Erdogan said on Tuesday the measures had significantly weakened the network of US-based cleric Fethullah Gulen, whose followers are accused of infiltrating state institutions and carrying out the coup attempt.
Erdogan, and many Turks, were angered by the Western response to the putsch, viewing it as more concerned about the rights of the plotters than the seriousness of the events.
He has also accused Europe of harbouring members of the Kurdistan Workers Party (PKK) militant group, which has waged a three-decade insurgency against the Turkish state and is deemed a terrorist group by the EU and US.
Erdogan is still seething over the presence of protesters sympathetic to the PKK near an EU-Turkey summit in Brussels in March, which he said at the time demonstrated the EU's "two-faced" behaviour.
