Yugoslav economy, led to mass unpopularity of the essential dictatorship of Slobodan Milošević and his allies in the Socialist Party of Serbia. In September 2000, amongst accusations of electoral fraud, large scale protests struck the nation. Milošević was eventually removed from power, as his Socialist Party of Serbia lost in the federal elections to the Democratic Opposition of Serbia. In the aftermath, a new government in Yugoslavia negotiated with the United Nations, accepting that it was not the sole legal successor to the Socialist Federal Republic of Yugoslavia, and was allowed to join the UN. Milošević would later be put on trial for corruption and war crimes, especially during the International Criminal Tribunal for the former Yugoslavia, although he died in prison before his trial could end in 2006. His culpability, especially of the charges brought against him in the context of the ICTY, remains a subject of controversy within Serbia. Gradual dissolution In 2002, Serbia and Montenegro came to a new agreement regarding continued co-operation, which, among other changes, promised the end of the name Yugoslavia (since they were part of the Federal Republic of Yugoslavia). On 4 February 2003, the Federal Assembly of Yugoslavia created a loose state union or confederacy—the State Union of Serbia and Montenegro, although Yugoslavia was still commonly used. A new constitutional charter was agreed to provide a framework for the governance of the country. On Sunday, 21 May 2006, Montenegrins voted in an independence referendum, with 55.5% supporting independence. Fifty-five percent or more of affirmative votes were needed to dissolve the confederation and Yugoslavia. The turnout was 86.3% and 99.73% of the more than 477,000 votes cast were deemed valid. The subsequent Montenegrin proclamation of independence on 3 June 2006 and the Serbian proclamation of independence on 5 June ended the confederation of Serbia and Montenegro and thus the last remaining vestiges of the former Yugoslavia. Politics The Federal Assembly of Yugoslavia, representing FR Yugoslavia (1992–2003) was composed of two chambers: the Council of Citizens and the Council of Republics. Whereas the Council of Citizens served as an ordinary assembly, representing the people of FR Yugoslavia, the Council of Republics was made equally by representatives from the federation's constituent republics, to ensure federal equality between Serbia and Montenegro. The first president from 1992 to 1993 was Dobrica Ćosić, a former communist Yugoslav partisan during World War II and later one of the fringe
