agenda of changing the party's voting system to a one-member-one-vote system which would give a numerical majority to Serbs. Montenegro also supported Serbia in opposing all reforms proposed by Slovenia that were deemed to be intended to devolve power to the republics. The Slovenian and Croatian communist factions abdicated the party in what they saw as an attempt by Milošević to create Serb hegemony in the party. The League of Communists collapsed, Bulatović followed the political changes in the other republics and made Montenegro a multi-party democracy and formed the Democratic Party of Socialists (DPS) with former communists. President of Montenegro (1990–1998) Siege of Dubrovnik (1991) On 1 October 1991, Peter Carington, 6th Baron Carrington came to Titograd and asked Bulatović if Dubrovnik was in danger of an attack by the Yugoslav People's Army. According to testimony by Nikola Samardžić to the ICTY, a member of Bulatović's cabinet, Bulatović promised Carrington that Dubrovnik would not be attacked. Just a few hours after meeting Carrington, Bulatović attended a meeting with several generals of the Yugoslav People's Army, including Pavle Strugar, after which Bulatović told Samardžić that "30,000 Ustashe are coming from Dubrovnik to seize the Bay of Kotor", and that a response was urgent. Bulatović ultimately participated in ordering an attempted annexation of Dubrovnik to Montenegro, additionally claiming that it was historically linked to Montenegro. After the war ended, Bulatović claimed that the attack on Dubrovnik was "the only way to prevent the conflict from spreading into Montenegro", but also asserted that the military gave the government of Montenegro "false information". Carrington's proposal (1991) The siege of Dubrovnik, in addition to war crimes committed, had enormous consequences for Yugoslavia's international standing. The European Economic Community invited Carrington and representatives from Yugoslavia to negotiate a peace accord known as the Carrington plan on 19 October 1991, in The Hague. The proposal of a "loose federation of independent states" was a non-starter for Milošević, who preferred a centralized Yugoslavia with institutional powers in Belgrade. Bulatović, to the shock of Milošević and his own party members, agreed to Carrington's terms and even signed a draft of the plan during an overnight session of the Montenegrin parliament on October 17, arguing that it would secure Montenegro's interests and end the Yugoslav wars. Bulatović's signature potentially guaranteed Montenegro's legal right to secede from Yugoslavia, resulting in an almost explosive rift with the Yugoslav leadership in Belgrade.
