Some 15,000 people have attended a rally in support of an independent Montenegro ahead of a referendum later this month. The meeting was addressed by the Montenegran President, Filip Vujanovic and the Prime Minister Milo Djukanovic. Serbia and Montenegro is all that is left of the six-member Yugoslav federation, which broke up in war in the 1990s.Serbia &m Montenegro’s initial federal interdependence became a loose alliance three years ago. A referendum will be held on May 21st. to decide whether the union of Serbia and Montenegro continues. A recent opinion poll found a small majority wants independence. The rules say 55 percent on a turnout of over half the electorate has to vote in favour of independence for it to be considered valid. The European Union has pushed a so-called double-track policy regarding political and economic reform in order to get both republics as close to the EU as possible.
