Serbian Prime Minister Vojislav Kostunica met today with a delegation of the Socialist International (SI), led by SI President Yorgo Papandreou and said that there is not a single condition for UN Special Envoy Martti Ahtisaari’s proposal on Kosovo-Metohija’s future status to be even considered by the UN Security Council since it is an illegal and illegitimate proposal which breaches the UN Charter and the Serbian Constitution.
