The parliament in Greece has narrowly approved a public sector reform bill that will see thousands of people lose their jobs.
In a 153-140 vote, MPs backed the bill tied to the country's fresh 6.8bn euros (£5.8bn) of bailout loans, needed to keep Greece afloat.
During the debate thousands of protesters rallied outside the parliament in the capital Athens.
Greece has recently been hit by a series of strikes against the cuts.
