Greece's government plans to put labour reforms demanded by foreign lenders to a parliamentary vote.
Finance Minister Yannis Stournaras said this is despite a junior coalition partner’s refusal to back them.
The government will present the 2013 budget law, which contains the bulk of new austerity measures demanded by lenders, in parliament on Wednesday.
It will present a separate bill with reforms including the contested labour measures a few days later.
Near-bankrupt Greece needs a comprehensive deal on the austerity package and reforms to unlock its next tranche of aid before it runs out of cash in mid-November.
Greece's gross public debt is equivalent to 171% of its economic output, according to the International Monetary Fund.
The Democratic Left party has the support of 16 deputies in the 300-seat parliament and the government, which has a 176-seat majority, could pass the package without its support.
But a vote against the package by the party would undermine the already fragile coalition and perhaps tempt other lawmakers to defect and vote against unpopular measures.
Greece has been locked in talks with its European Union and International Monetary Fund lenders on the austerity package for months, but a final agreement has been held up by Democratic Left's objections.
The government of Prime Minister Antonis Samaras is still hoping the party, led by moderate leftist Fotis Kouvelis, changes its stance, but was prepared to move ahead without its support, a government official said.
"From the government's side we want to be ready on everything relating to the budget, reforms ... with or without Kouvelis's agreement," the official said.
