Angry Montenegrin separatists, opposed to the new federal agreement between Montenegro an Serbia, forced Montenegrin Prime Minister Filip Vujanovic to resign from office. Vujanovics resignation led to an immediate collapse of his government. This leaves Montenegrin President Milo Djukanovic (who is, or was?, an avowed separatist, but signed the agreement anyway) politically isolated. Whats next? New elections, with the Serbia-Montenegro union the central issue.
