The vote was expected to be held on Thursday, but the leaders of parliamentary groups unanimously decided to postpone it, according to the AMNA news agency.
Greece and Macedonia, officially known as the Former Yugoslav Republic of Macedonia (FYROM), have been entangled in a naming dispute for years, with Athens opposing the use of "Macedonia," which is also the name of a region in Greece. The agreement on the new name for Macedonia – Republic of Northern Macedonia – was signed by Macedonian Foreign Minister Nikola Dimitrov and his Greek counterpart Nikos Kotzias on June 17.
The deal paved the way for Macedonia to join the European Union and NATO, which had been earlier blocked by Greece over the naming issue. Earlier this month, the deal was supported by the majority of Macedonian lawmakers, while the Greek parliament is still to ratify the document.
The Prespa agreement is widely criticized by various political forces in Greece, who have been staging massive protests in Athens.
