BRATISLAVA, May 21 (Reuters) - Support for the Slovak leftist SMER party of Prime Minister Robert Fico has slipped, opening the possibility that a wide centre-right coalition could unseat the government after an election next month, an opinion poll showed on Friday.
The survey by FOCUS agency showed backing for SMER fell 1.5 percentage points from a month ago to 35.3 percent, slightly cutting its lead ahead of the strongest opposition SDKU party which gained 0.6 point to 14.0 percent.
The Slovak parliament will be highly fragmented and the poll showed that SDKU, the party set up by former right-wing prime minister Mikulas Dzurinda who won praise for pro-market reforms in 2002-2006, and four other parties could win as many seats as the ruling coalition.
The poll showed five SDKU, Freedom and Solidarity (SaS), the Christian Democrats (KDH) and two ethnic Hungarian factions, SMK and MOST-HID, would win 75 seats in the 150-seat parliament, a perfect stalemate.
The result is however highly uncertain given the margin of error for each party. Four parties polled only slightly above the 5 percent threshold needed to win parliamentary seats.
A stalemate would mean that Fico would need to find more or different coalition partners than the far-right Slovak National Party (SNS), and the HZDS party of former authoritarian prime minister Vladimir Meciar. The next government will have to slash down the fiscal deficit, after Fico's cabinet pledged to cut the gap to 5.5 percent of gross domestic product this year and below the EU's official limit of 3 percent of GDP in 2012.
Fico has campaigned hard on pledges not to cut welfare amid the economic crisis, with the help of the export-fuelled economy that is rebounding at the fastest rate in the EU.
A spat with Hungary over the treatment of half a million-strong Hungarian minority in southern Slovakia has soured the pre-election campaign, and raised tensions with Budapest.
The Hungarian right-wing Fidesz party, which won election in April, plans to ease citizenship claims for Hungarians living abroad.
Investors have called for further structural and market reforms, adjustment of the legal system, better law enforcement and a fight against flourishing corruption, a problem in ex-communist countries, which joined the European Union in 2004.
