March 25 (Reuters) - The ousting of the Czech government upped political nerves in the European Union's eastern members on Wednesday. Hungary continued its search for a new administration and its president said an early election would be the best way forward.
Following are thumbnail sketches of Eastern Europe's coalition governments and recent flashpoints:
* BULGARIA -- The poorest EU nation has been hit by protests demanding the government shore up the economy although analysts say accelerating public discontent ahead of an expected summer election is unlikely to cause the government to fall.
-- Bulgaria's opposition right wing GERB party extended its lead in a January Gallup poll over the ruling Socialists and is expected to win the most votes in the election.
* CZECH REPUBLIC -- The Czech opposition Social Democrats won a no-confidence vote on Tuesday on the centre-right coalition of Prime Minister Mirek Topolanek.
-- Topolanek said he should lead any new government, despite losing the vote. President Vaclav Klaus has the sole right to appoint a new prime minister and until then the three-party coalition will remain in office, possibly until the end of its EU presidency at the end of June.
-- The ousting could threaten Czech ratification of the EU's Lisbon treaty and cast more doubt on an already sidelined plan to build a U.S. missile defence radar system in the country.
-- Czech banks have been relatively unaffected by the global financial crisis, but growth has been hit badly by deepening recession in Western Europe, which has led to a sharp drop in output and job losses in the key manufacturing sector.
* HUNGARY -- The Socialists want opposition backing to pass a no-confidence vote in outgoing Prime Minister Ferenc Gyurcsany and approve the new prime minister in April, avoiding holding an election which the main opposition party Fidesz would likely win. Gyurcsany said last Saturday he was ready to step aside for a new government to lead Hungary out of the economic crisis.
-- The Socialists are seeking agreement with opposition parties, mainly the Free Democrats and the Democratic Forum, on the new leader. The Socialists have ruled in a minority since last April. The next general election is due in 2010.
-- Hungary sought a $25.1 billion IMF-led rescue package last year to stave off financial crisis, after falls in its forint currency had borrowers struggling to pay foreign currency loans and endangered banks. Hungary's economy contracted by 2.3 percent in the fourth quarter of last year.
* LITHUANIA -- Police fired teargas in January to disperse demonstrators who pelted parliament with stones in protest at cuts in social spending to offset the slowdown.
-- The four-party centre-right coalition in office since October has raised taxes and cut spending to shore up the budget as revenues fell.
* POLAND -- The ruling centre-right Civic Platform led by Prime Minister Donald Tusk is ahead of its rivals with 44 percent of Poles saying they would vote for it if an election were held tomorrow. The next parliamentary election is not due until 2011 unless the government holds an earlier vote.
* ROMANIA -- Parliament approved the 2009 budget on Feb. 20 earmarking more than 10 billion euros ($12.85 billion) to lessen the pain of sharp economic slowdown with a consolidated deficit target of 2 percent of gross domestic product, against the 5 percent shortfall recorded in 2008.
-- The International Monetary Fund agreed a 20 billion euro aid package with Romania, including 12.9 euros of IMF money and 5 billion euros from the EU, on Wednesday.
-- Elections in November brought in a coalition of former archrivals as the Social Democrat Party and Democrat-Liberal party came neck and neck in the polls.
-- The government is expected to be strained by a presidential election in November and suffered a blow in January when the interior minister resigned after a row with coalition partners over the appointment of an intelligence chief.
* SLOVAKIA -- Prime Minister Robert Fico won 2006 elections promising to spend more on the poor. The government approved a 332 million euro stimulus plan in January aimed at easing the impact of the economic slowdown.
-- Slovakia's unemployment rate rose to a 29-month high of 9.72 percent in February, as the euro zone's youngest member felt the hit of economic crisis in its main export markets.
* UKRAINE -- The pro-Western "orange revolution" coalition was reinstated last December with Prime Minister Yulia Tymoshenko still in situ, effectively ruling out for now the prospects for a snap election.
-- Ukraine's political volatility predates the impact of the financial crisis, which has savaged the steel and banking sectors. Industrial output has shrunk by more than a third, the worst drop in over a decade.
-- Ukraine has clinched a $16.4 billion loan deal with the IMF to help offset the effects of the world financial crisis. But the Fund has suspended release of the loan's second tranche while discussions proceed on several issues, including the size of the budget deficit.
