Government spokesman Gabriel Sakellaridis acknowledged the vote laid bare a split in Syriza, but he said the government's priority was to secure the bailout.
The result of the bailout vote in Parliament is a "major split in the unity of Syriza's parliamentary group," Sakellaridis told reporters after the vote early Thursday.
The Greek parliament passed the new austerity-for-credit measures with 229 votes in the 300-seat chamber. Sixty-four lawmakers opposed the cuts on the table and six abstained.
Among those who opposed the bill were 32 members of Prime Minister Alexis Tsipras’s Coalition of the Radical Left, or Syriza.
Syriza had come to power in January on pledges of putting a stop to five years of austerity.
"Thirty-two MPs decided not to back the government of the Left, voting against its choice to prevent the risk of bankruptcy," Sakellaridis said.
"The prime minister's, and the government's, top priority is the successful completion of the agreement very soon."
