Six parties that passed the 5 percent threshold in June 17 general elections will comprise the 150-seat parliament.
The leftist Smer-Social Democratic Party led by Robert Fico won the most votes and will lead the coalition with the right-wing Slovak National Party and the People's Party-Movement for a Democratic Slovakia, led by autocratic ex-Prime Minister Vladimir Meciar.

Slovak President Ivan Gasparovic will appoint the new Cabinet, led by Fico, later Tuesday, following the formal resignation of the outgoing government of Mikulas Dzurinda.
