Greek conservative party head Antonis Samaras has been sworn in as prime minister at the helm of a three-party coalition that will uphold the country's international bailout commitments.
The move ends a protracted political crisis that had cast grave doubt over the country's future in Europe's joint currency and threatened to plunge the eurozone deeper into a financial crisis.
Mr Samaras, an American-educated 61-year-old economist, was sworn in three days after his party won the second national election in six weeks but without enough votes to form a government on its own.
His New Democracy party will join forces with the socialist PASOK party, which came in third place, and the smaller Democratic Left led by Fotis Kouvelis.
All three parties broadly back Greece's pledges to bailout creditors for further austerity and reforms, although they have pledged to renegotiate some terms of the rescue loans.
New Democracy and PASOK are also looking for an extension of at least two years in the deadlines for implementing fresh cutbacks.
Democratic Left leader Fotis Kouvelis went a bit further, saying that Greece should eventually "disengage" from the austerity commitments.
Greece has been dependent on loans from the eurozone and International Monetary Fund since May 2010.
In return, it has imposed deep spending cuts, slashed salaries and pensions, and repeatedly hiked taxes.
The measures have left the country struggling through a fifth year of recession, with unemployment spiralling to above 22%.
