BRATISLAVA, April 4 (Reuters) - The Slovak ruling coalition's majority shrank in February after a junior government party ousted one of its deputies for voting with the opposition.
The euro zone country has experienced a series of coalition clashes since the four-party government led by Iveta Radicova took power last summer on promises to fight political cronyism and worsening trends in public finances.
The ouster of Igor Matovic from the liberal Freedom and Solidarity (SaS) party reduced the coalition's ranks to just 77 in the 150-seat parliament, denting its power to push through reforms plans in the central European country.
Three of Matovic's colleagues, the 'Common People' faction, have said they would eventually also quit SaS after forming a new independent political party, but not in the coming weeks or next few months.
The coalition already lost one deputy in January.
Below are key political risks to watch:
SMALL MAJORITY, COALITION SQUABBLES
The coalition, which took power in July, has had several internal clashes over policy, including tax hikes proposed by the SaS and a row over the election of a new state prosecutor, sparking political distrust.
The prosecutor's row triggered the most serious rift, with Radicova threatening to quit in a warning to a backbench revolt in the parliament and members of the coalition accusing each other of violating joint agreements.
The government has agreed to make the secret vote on the prosecutor public and the parliament was expected to hold a renewed vote in April.
What to watch:
-- Rising tension in the coalition. The coalition is vulnerable to rebellions and the strongest opposition party SMER of ex-Prime Minister Robert Fico remains the most popular party.
-- The ousted SaS legislator Matovic has announced plans to establish a new independent political party, which may lure away more government deputies. Matovic has however vowed not to try bring down the cabinet.
UNHAPPY UNIONS
The government is facing union resistance to cuts in public spending, tax hikes and planned changes to the labour code.
Thousands of union workers protested against the austerity package, but the cabinet is highly unlikely to go back on measures already passed.
Government, business and unions are negotiating a revision to the labour code. The government proposed to roll back the extra powers given to the unions by the last government and increase labour market flexibility, hoping to reduce unemployment of over 13 percent and attract new foreign direct investment. It is unclear when a bill could come to parliament.
What to watch:
-- a debate on an amended labour code could trigger more clashes between employers and unions. Unions have said they are ready to stage new protests.
-- The government presented its first working version of the code on Jan. 31. The unions said they needed time to study the document. The final version is due in April.
SLOVAK-HUNGARIAN RELATIONS
The two neighbours have a history of discord, with Hungary accusing Slovaks of oppressing its ethnic kin, and Bratislava bristling at its former imperial master's efforts to promote Hungarian culture in Slovakia.
Radicova's coalition includes the Most-Hid party, representing mostly ethnic Hungarians, which has acted as a moderating influence on the fractious relationship.
Bratislava and Budapest want to ease tensions over dual-citizenship laws and will start talks on doing so next month.
The coalition struggles to agree a joint stance whether to scrap or only soften a law stripping people of their Slovak citizenship if they take the citizenship of another country.
Radicova said she wanted a bilateral treaty on the issue. Hungarian Prime Minister Viktor Orban said it was a possibility.
What to watch:
-- Further actions by both Bratislava and Budapest on the law, timeframe, nature of the new code and reaction from the Hungarian minority in Slovakia.
-- Slovaks have submitted a draft law to Budapest in February. Hungary has to study the proposal.
CORRUPTION, BUSINESS CLIMATE
The government says it wants to improve the business climate, crack down on corruption and boost law enforcement -- major concerns for investors under the previous leftist government.
Transparency International's latest corruption perception index showed Slovakia ranked in joint 59th place in the world 2010, lower than its Central European neighbours Poland, Hungary and the Czech Republic.
What to watch:
-- The parliament approved a law on judges, the first step in a judicial reform designed to increase the transparency of a system long criticised by the public and investors.
-- The government has pledged to increase the transparency of public procurement projects, publish government tenders online and enhance the functioning of the courts to reduce delays.
-- The government also plans to ease labour market regulation and boost flexibility.
