Greece's main opposition party will vote against austerity measures in the bailout bill, even though its leader Antonis Samaras conceded they agree on some measures and respect the deal.

"These measures are a wrong policy mix that will send the country into dead end of deeper recession and even more austerity to come," Samaras said. "This medicine can kill the patient."

Samaras, leader of the conservative New Democracy Party was speaking in Parliament ahead of a vote on the bill due Thursday afternoon.

Samaras said the ruling socialist PASOK had turned the debt crisis into a borrowing crisis and now Greece is under the control of foreign organizations in exchange for a EUR110 billion aid deal from the International Monetary Fund and the European Union.

"Out of the EUR30 billion of cuts over the next four years that are mandated under the bill, EUR11 billion has yet to be outlined so we don't know what we are voting on," Samaras said. "New austerity measures may come and we won't give a blank check for them."

He also criticized the government's lack of measures for economic stimulus, its lack of consideration of privatization, nor the utilization of state real estate holdings which could total EUR300 billion, roughly equivalent to the national debt.

The conservative leader said his party agreed on some of the new measures, such as support for poorer social classes, support for banking system liquidity and hiking excise taxes on cigarettes and alcohol.

The New Democracy leader conceded that given PASOK's safe parliamentary majority the bill would pass, so there was no absolute need for his party to vote for it.

"The Greek state has continuity and we will respect and guarantee any agreement taken today and can assure that the funds will be paid back," Samaras said.
