BUCHAREST, Romania - Romania's government fell Friday in a no-confidence vote, as opposition parties seized on widespread public anger over biting austerity measures, cronyism and corruption.

Some 235 lawmakers voted against the government of Prime Minister Mihai Razvan Ungureanu, four more votes than needed.

Opposition leader Victor Ponta said the vote represented the end "of an abusive system that uses any weapon possible."

"Sometimes there is justice. Today there was justice," he declared.

President Traian Basescu nominated Ponta as the prime minister-designate and asked him to present a governing program and Cabinet to Parliament for approval.

Calling for calm, Basescu said: "There was a democratic process in Parliament. There is no reason for panic. Romania's finance ministry has substantial reserves that can cope with any event."

The Czech government also faces a vote of no confidence Friday, which it is expected to survive amid growing public anger against austerity measures and corruption.

Former Romanian Prime Minister Emil Boc, whose 4-year-old government was toppled in February after weeks of often violent protests over austerity measures, called the vote "a victory for opportunism in politics and party swapping."

However, he added: "I take responsibility for this failure."

Romania's national currency, the leu, fell close to an all-time low on the news.

Thousands of people have protested in both Romania and the Czech Republic in recent months, calling for their governments to abandon the belt-tightening measures and resign, in some of the biggest rallies seen since the overthrow of communism in 1989.

Boc called on the Romanian opposition to "immediately" take on the responsibility of governing the country to avoid political and economic instability.

"Any moment of instability means Romanians losing money from their pockets," he said after meeting Basescu.

In Prague, Prime Minister Petr Necas vowed to continue with reforms and cuts if the government survives the Czech vote of no confidence.

"We have to take the steps today. If we postpone them, we will have to adopt them anyway but they will be much more painful," he told lawmakers.

Bohuslav Sobotka, chairman of the major opposition Social Democrats, said it was not normal for the government "to exist when it ignores the mass protests of citizens in the streets."

About 100,000 people rallied in Prague on Saturday, calling on the government to scrap the cuts and leave office. The following day, leaders of the three parties in the centre-right government dissolved their coalition. The split was triggered when Vit Barta, a prominent member of the centrist Public Affairs party which ran on an anti-corruption ticket in 2010, refused to resign after being convicted of paying bribes.

Czechs are angry about a sales tax hike and an extra 7 per cent income tax slapped on high earners. The government has also revised earlier promises to increase pensions and introduced a new entrance fee for university students. Unions say health and pension reforms will hurt ordinary people the most. The Social Democrats have surged in opinion polls.

In Bucharest, the government hiked the sales tax to 24 per cent and slashed public sector wages by one-fourth to meet the conditions of a euro20 billion ($26 billion) bailout it took from the International Monetary Fund, the European Union and the World Bank in 2009.

"We don't want any more dubious firms, no more selling under the market price and huge bribes as we have now," said Ponta, leader of Romania's opposition Social Democracy Party.
