As Alexis Tsipras took his oath as Greek prime minister for the second term, he promised his country the revival of its flailing economy.

Tsipras’ Syriza party won 145 seats out of 300 total seats in the snap election this week, after the left-wing political leader resigned on Aug. 27.

"We are committed and dedicated to do anything in our power in order for the country and the people to exit this tremendous hardship, for our country to become once again powerful, an equal partner within the European Union and our people proud and dignified," SBS quoted the newly elected Greek prime minister as saying.

Stelios Kouloglou, the Syriza representative at the EU, said there was no time for celebrations over Tsipras’ victory. He, however, acknowledged to the ABC that it was a “big victory.”

Tspiras and his Syriza party got the benefit of doubt from Greek voters and secured an unexpectedly clear mandate in their favour. However, Tspiras has a tough job ahead as the European Commission reminds him that he has “no time to lose.”

"On behalf of the European Commission, I would like to congratulate you on the electoral results of last night," the ABC quoted president Jean-Claude Juncker’s letter to Tsipras. "I am confident that this provides the basis for your new government to be formed swiftly and to use the democratic mandate to move forward" on implementing the three-year bailout deal agreed in August.”

Juncker said there was an “urgent need to operationalise the management of the refugee crisis." He said Greece could count on the commission which would stand by the new government in its efforts.

According to an official from the Syriza party, Tsipras’ first priority will be to stabilise banks.
