ATHENS — Under the threat of yet another deadline, the Greek Parliament approved a second package of policy changes early Thursday that the country’s creditors had said must be in place before the detailed negotiations for a bailout of 86 billion euros could begin.

The new measures, overhauling the banking and judicial systems, passed easily with significant support from opposition parties eager to do whatever it takes to keep Greece from leaving the eurozone. The vote was 230 to 63, with five abstentions and two absences.

Prime Minister Alexis Tsipras was able to win over only two additional members of his leftist Syriza party compared with the first major vote last week on the bailout accord. Most of the party’s hard-liners continued to rail against what they said was the creditors’ “blackmail” and voted no, making it likely that new elections would be held in the fall.
