18 countries completed the ratification procedure, four countries ratified the agreement, but did not send the documents to Brussels, while four countries ratified the agreement in one of the chambers of parliament, Europeiska Pravda reported on July 09. Only two countries - Greece and Cyprus - have not held a single vote on the issue.
