Greece's freshly-elected Prime Minister Alexis Tsipras unveiled his new cabinet on Tuesday, giving the crisis-hit country's key finance portfolio back to Euclid Tsakalotos, a leftwing economist determined to keep Greece in the euro.

The 55-year-old Oxford-educated Tsakalotos faces the thankless task of steering a slew of unpopular economic reforms agreed by Tsipras with Europe's leaders in July, in return for Greece's third financial rescue in five years.

The new cabinet, announced by its spokeswoman Olga Gerovassili, is largely a carbon-copy of Tsipras' outgoing leftwing government.

But Tsipras confounded his critics, romping to a clear reelection victory on Sunday. Five seats short of a majority in the 300-member parliament, he once again formed a coalition with his 'odd couple' partner of the previous government: the nationalist Independent Greeks party.

Tsipras, whose Syriza party was elected in January on an anti-austerity plank, has said he finally agreed to the harsh belt-tightening measures set by the cash-for-reform agreement in order to keep Greece in the euro.

The 41-year-old premier had vowed to have the government up and running before he heads to Brussels on Wednesday to join EU leaders for talks on the migrant crisis.
