* Czech govt loses no confidence vote, crown suffers
* Hungary searches for PM, politics start to weigh on region
* Romania grabs 20 billion euro IMF/EU deal
* Budget pressures show in Poland, interest rates cut

PRAGUE, March 25 (Reuters) - The ousting of the Czech government upped political nerves in the EU's eastern members on Wednesday, putting regional currencies on a weaker footing as markets also watched the search for a new government in Hungary.
Centre-right Prime Minister Mirek Topolanek lost a vote of confidence on Tuesday, complicating his government's efforts to fend off economic troubles that have driven three of the region's once-booming states to seek rescues from the International Monetary Fund.
Topolanek's defeat, which means his cabinet must resign but will stay on while politicians bicker over a replacement or an early election, followed a weekend decision by Hungary's prime minister to step aside.
It also came as the IMF announced a 20 billion euro bailout for Romania, following deals for Latvia and Hungary, and as budget pressures arose in Warsaw. [
] [ ]The reasons behind the Czech and Hungarian government falls differed, with Hungarian Prime Minister Ferenc Gyurcsany's decision to step down tied to the economic crisis and Topolanek's due to domestic political squabbles. [
]But market watchers agreed it was a step backwards for a region fighting to contain a credit crunch, an outflow of investment, a fall in manufacturing and rise in unemployment.
"For the time being we will have a weak (Czech) government and that in itself is not good for a rapid response to what is a weak global backdrop," said Martin Blum, emerging strategist with UniCredit in Vienna.
"The bottom line is it is an added negative for the region."
The crown lost 1.2 percent against the euro from the previous session, while the forint recovered from early losses to trade flat at around 299.5. The zloty was down a touch at 4.552 per euro after the central bank cut interest rates to a historic low on Wednesday. [
]The Czech currency has outperformed this year with just a 2 percent loss, versus 6-12 percent falls for regional peers.
NO QUICK FIX
Analysts expected Budapest's search for a new government, tasked with leading the country out of economic turmoil, to be quicker than Prague's, where domestic squabbling risks clouding leaders' focus in coming months.
Former Hungarian central bank chief Gyorgy Suranyi sought support from all political parties on Wednesday, looking like the front-runner among possible candidates. [
]But the Czech opposition refused to support any bid by Topolanek to form a new government, a possibility under the constitution, signalling the battle leaders have before them.
"You can understand why oppositions do this, but it is almost like cutting off your nose to spite your face," said Stuart Bennett, a currency strategist for Calyon bank.
Some analysts also warned the Czech impasse might signal a new phase of the crisis in emerging Europe, which could possibly give rise to populism and hurt reforms needed for growth.
"Any retreat to populism could make the difference between the region growing at around 5 percent per annum over the next ten years, and the region growing just 2 percent," Capital Economics wrote in a note.
Forecasts on Wednesday showed Poland's first-half budget deficit was expected to be at more than 90 percent of the full-year plan, indicating spending cuts were needed. Officials promised they would hit their targets by the end of 2009.
In Romania, news of an IMF lifeline, which had been flagged to markets for the last month, pushed the leu 0.4 percent up to 4.27 to the euro. But analysts said a deal was not a save-all.
"The severity of the recession facing many countries in emerging Europe will obviously have an adverse impact on unemployment and the public finances, in some cases requiring budget austerity measures," said Edward Parker, head of emerging European sovereigns at Fitch ratings agency.
"Such dynamics run the risk of increased political uncertainty and event risk." (Additional reporting by Peter Apps in London; editing by Patrick Graham)
