(ANSA) - BELGRADE, OCT 16 - Slovakian Prime Minister Robert Fico's expulsion from the Party of European Socialists will be formalised tomorrow at the Congress in Amsterdam. "It is up to the EPP to decide on Vučić's continued membership, as we do not interfere in other groups' affairs."What I can say is that the PES congress starts today in Amsterdam, and tomorrow's agenda includes the definitive expulsion of Fico's party, Smer-SD. I believe this is a message to all autocrats," Croatian Socialist MEP Tonino Picula told reporters during a briefing in Brussels. (ANSA).
