CROATIA: Zoran Milanovic, Prime Minister since December 23, 2011. He has also been the leader of the Social Democratic Party of Croatia (SDP), the largest centre-left political party in Croatia, since 2007. Milanović's foreign policy was concentrated on the accession of Croatia to the EU. On 1 July 2013, Croatia joined the European Union, becoming the 28th member state. Milanović's time in office has been marked by several cuts to Croatia's credit rating.
