Prime Minister Alexis Tsipras is widely expected to reshuffle his Cabinet, following a rebellion within his party over a parliament vote to approve painful austerity measures demanded for new bailout talks to start.
The reshuffle was expected Friday or over the weekend.
In the early hours of Thursday, 38 of Tsipras' own radical-left Syriza party members dissented and vote against him. They included two cabinet members — the energy and welfare ministers — as well as the parliament speaker and the former finance minister, Yanis Varoufakis.
The legislation, which includes consumer tax increases and pension cuts, was part of conditions demanded by Greece's European creditors in order to start negotiations on a third bailout, worth about 85 billion euros ($92 billion).
