Greece's parliament has approved new measures of austerity before a eurozone finance ministers meeting in Brussels on May 22.
The legislation was passed by all 153 deputies in Prime Minister Alexis Tsipras' ruling coalition.
Earlier, Greece and a group of international creditors reached a preliminary agreement on the allocation to Athens a 7.5 billion euro bailout tranche in order to support the national economy.
The third economic adjustment programme for Greece in the amount of €86 billion was agreed in mid-2015 and ends next year.
