Portugal's parliament has voted to adopt a tough austerity budget for 2012 that leaders hope will rescue the country's crippled economy despite the risk of worsening social unrest.
Just days after thousands of workers descended onto Lisbon's streets to join a protest strike, MPs passed the unpopular budget package that cuts salaries, raises taxes and increases working hours for vast numbers of workers already squeezed by recession.
"This is doubtless the toughest budget since Portugal became a democracy" in 1974, Finance Minister Vitor Gaspar told MPs during the budget session on Wednesday.
"This budget is necessary to renew the confidence of the Portuguese people, of the markets and of our international partners," he added.
The bill was backed by the centre-right majority in parliament but triggered bitter opposition from the unions and the socialist opposition who boycotted the vote.
"It is a bad budget ... that contributes nothing to the economy and nothing to growth," said socialist leader Antonio Jose Seguro.
On November 24 unions opposed to the bill called a general strike, shutting down Portugal's transport system and triggering protests throughout the country.
Faced with massive popular discontent, the centre-right coalition opted to ease some measures after the budget bill passed a first reading in parliament on November 11. Thus the suspension of 13th and 14th month salary payments for civil servants will now affect only those earning more than 1,100 euros ($A1,468) a month rather than 1,000 euros.
That concession will cost state coffers 130 million euros, which will be covered by higher taxes on capital revenues.
However the 30-minute extension of daily working hours for private sector employees was maintained in the final legislation.
Also maintained were health and education spending cuts and a rise in VAT on a range of products including a leap from 13 to 23 per cent for the restaurant trades, which owners say could result in the closure of 21,000 eateries.
After Greece and Ireland in 2010, Portugal became the third eurozone member state needing a bailout in May when it could no longer raise fresh funds at sustainable rates on the financial markets.
Portugal was handed a 78 billion euro loan in exchange for a pledge to reduce its public deficit from 9.8 per cent of gross domestic product in 2010 to 4.5 per cent by the end of 2012.
The Portuguese economy is expected to shrink by three per cent in 2012 and unemployment set to rise to a record rate of 13.4 per cent.
The finance minister told parliament that the government was confident it would meet its target of cutting the deficit to 5.9 per cent by the end of this year.
