Greek lawmakers approved tax increases and a new privatization fund on Sunday and freed up the sale of non-performing loans in exchange for much-needed bailout loans and debt relief.
"Greeks have already paid a lot, but this is probably the first time that the possibility of these sacrifices being the last is so evident," Prime Minister Alexis Tsipras told lawmakers before a vote in parliament.
His left-led coalition, re-elected in September on pledges to implement the terms of a 86-billion euro bailout it signed up to in July, has a narrow majority of 153 lawmakers in the 300-seat parliament.
The coalition voted in favor of the reforms with only one MP against some articles on the new privatization fund and a contingency mechanism of spending cuts that will be activated only if Athens looks set to miss its fiscal targets.
Syriza MP Vassiliki Katrivanou later resigned saying in a post she uploaded on Facebook that: "we are implementing measures and policies which are against the core of our values." Her resignation will not affect the government's majority since she will be replaced.
