(ANSA) - BELGRADE, FEBRUARY 28 - Slovakia is heading to the polls on Saturday for its eighth parliamentary election since independence, with polls suggesting that a newcomer, the party OL'aNO, may challenge the incumbent Social Democratic party of former PM Robert Fico, with surveys indicating a worrying rise of the far-right. Voters will cast their ballot for renewing the 150 members of the National Council, the only house of parliament, few days after the second anniversary of the murder of journalist Jan Kuciak and his fiancée, a case that shook Slovakia, brought thousands to the streets and led to the resignation of Prime Minister Robert Fico. The parties currently in government, SMER-SD (social conservatives), SNS (Slovak National Party, nationalists) and the Hungarian party Most-Híd (Bridge) are "losing public support," an analysis of the Vienna Institute for International Economic Studies (wiiw) shows. A survey of Zdroj-Agentura Ako confirmed that the SMER-SD could acquire the support of 16.9% (-11.4% compared to 2016) of the voters. The SNS, with 5.0% (-3.6%) and Most-Hid 4.7% (-1.8%), are risking not to pass the 5.0% election threshold. The opposition OL'aNO (Ordinary People and Independent Personalities), an anti-corruption movement led by Igor Matovic, could win 15.5% (+4.5%), while the recently formed PS/SPOLU (Progressive Slovakia/Together), with 9.4% and Za L'udi (For the People, 8.9%) "are on the rise," the analysis said. However, "the most worrying trend is the strong support for the extreme far-right L'SNS (People's Party - Our Slovakia), which is, according to the polls, currently the third most popular party," with 10.3% (+2.3% compared to 2016). Another poll, released recently, put OL'aNO for the first time in front of SMER-SD. (ANSA).
