BRATISLAVA (Reuters) - Slovakia`s parliament will hold its first session since last month`s general elections on October 29, a senior parliamentary official said on Wednesday. "The new parliament will vote on a new chairman and all the bodies at its first session," Jan Knapp told Reuters. An alliance of four opposition parties handed Prime Minister Vladimír Mečiar a heavy defeat in a general election at the end of September and are now locked in negotiations on forming a government. However, no one has yet been officially appointed to lead talks on the creation of a new cabinet. By tradition the largest single party, in this case Mečiar`s Movement for a Democratic Slovakia (HZDS), is given the first chance to form a government. The current chairman of parliament Ivan Gašparovič has indicated that this is what he will do. However the four opposition parties, who have expressed a common will to form a government and hold a huge majority in parliament, say this would simply be a waste of time. The leaders of the former communist Party of the Democratic Left (SDL), the Hungarian Coalition Party (SMK), the Slovak Democratic Coalition (SDK) and the Party of Civic Understanding (SOP), have said they will meet Gašparovič on Thursday to urge him to change his mind. The four opposition parties won 93 of the 150 seats in parliament in the September 25-26 election. SDL chairman Jozef Migas said earlier this week he expected the new government to be formed by mid-November at the latest.
