The status of the union between Montenegro and Serbia was decided by a referendum on Montenegrin independence on 21 May 2006. A total of 419,240 votes were cast, representing 86.5% of the total electorate; 230,661 votes (55.5%) were for independence and 185,002 votes (44.5%) were against. This narrowly surpassed the 55% threshold needed to validate the referendum under the rules set by the European Union. According to the electoral commission, the 55% threshold was passed by only 2,300 votes. Serbia, the member-states of the European Union, and the permanent members of the United Nations Security Council all recognised Montenegro's independence.
