PM George Papandreou has said that only his 28bn-euro (£25bn) austerity plan would get Greece back on its feet.
If the package is not approved, Greece could run out of money within weeks.
Without a new plan in place, the EU and IMF say they will withhold 12bn euros of loans which Greece needs to repay debts due in mid-July.
