Prime Minister-designate Omar Karami has dispatched members of his outgoing Cabinet to hold final talks on the viability of a national unity government, with one envoy saying Karami will once more step down if the talks fail to reach an agreement. Karami, who was reappointed earlier this month after resigning on February 28, insists on forming a national unity government, but opposition figures have refused to join any government, saying he must form a Cabinet without them and hold parliamentary elections expected on time this spring.Opposition figure Batroun MP Butros Harb met with Speaker Nabih Berri Tuesday to "discuss the last developments." Harb said: "It was an opportunity to talk about the next stages the country could face in the event an agreement is reached over the Cabinet formation, and on the contrary in case of no agreement." He hoped the next Cabinet would be able to handle the responsibilities concerning the elections, the international investigation into former Premier Rafik Hariri's assassination and the opposition's call for the resignation of the country's security chiefs. Karami has been trying to hold talks with political and religious leaders in order to assemble a national unity government.
