Greece's euro partners are unlikely to sign off the release of the country's next batch of bailout cash at a meeting next week, even though its Parliament narrowly backed more unpopular austerity measures early Thursday.

Germany's Finance Minister Wolfgang Schaeuble said the eurozone is not yet in a position to make a decision on releasing the funds, as many in Athens had hoped. The 17 euro finance ministers are due to meet on Monday.

"We're not there yet," Schaeuble said in Hamburg.

"I don't see how we would get to a decision next week," he said. "Not all is lost, but not all is won."

The approval of the austerity bill early Thursday, which will further cut salaries and pensions and increase taxes, was a key step towards persuading Greece's international creditors to release the next €31.5 billion ($40.15 billion) installment of the country's vital bailout loans.

Without it, the government has said the country will start running out of cash Nov. 16. Schaeuble's comments suggest an interim financial arrangement may have to be agreed.

Germany, the biggest single contributor to Europe's bailouts, has insisted Greece must first pass its 2013 budget to create the basis on which the country's creditors can make a decision to release the new funds.

That vote is scheduled for Sunday and will come as another test to the coalition government of Antonis Samaras. Parliament's vote in favor of €13.5 billion worth of spending cuts and tax increases came at a cost for the fragile three-party coalition government

Lawmakers voted 153-128 for the package, hours after more than 80,000 protesters demonstrated outside on the streets of Athens — some fighting running battles with riot police.

Only two — the majority conservatives and the Socialists — of the three parties in the coalition backed the austerity package. But there was also dissent in those ranks, with seven lawmakers expelled for failing to back the measures and an eighth saying he was leaving the Socialists to continue as an independent member of parliament.

Nevertheless, the government is not in imminent threat of collapse as the third party, the Democratic Left, which abstained from the austerity vote, insists it will continue as a coalition member. The three parties are expected to present a united front in the budget vote.

Greece has relied on rescue loans from its euro partners and the International Monetary Fund since 2010. In return, it has had to implement a series of austerity measures which have hit the economy hard. Greece is set to enter its sixth straight year of recession.

Figures Thursday showed unemployment figures up at 25.4 percent in August, increasing from 24.8 percent in July and 18.4 percent the year before. More than 1.2 million people in this country of barely 10 million are now unemployed, with 58 percent of all young people aged 15-24 are unemployed.
