Greek Prime Minister-elect Alexis Tspiras said on Monday his government would focus on restoring stability in the economy and the country’s banking system, and discussions with lenders for debt relief.

“The mandate that the Greek people have given is is a crystal clear mandate to get rid of the regime of corruption and vested issues”, he said.

Greece’s left-wing Syriza party has been re-elected after winning 35.5% of the vote.

But the new coalition is likely to have a slightly narrower majority of 155 seats in the 300-seat parliament, compared with 162 seats over the period from January to August, initial results showed. It guarantees it 145 seats in the Greek parliament, which has a total of 300 members.

On the other side of the Greek capital New Democracy voters were less than confident Tsipras will deliver stability and expressed fears that his actions will worsen one of the worst depressions to hit an industrialised country in modern times.

Tsipras expects to form a government within three days, another party source said.

“After years of nearly unprecedented crisis, the vast majority of Greeks are endorsing parties that are promising to keep the country in the euro even if that implies thorough and painful reforms”, Holger Schmieding, chief economist at Germany’s Berenberg bank said.

However, he warned of difficulties ahead and said economic recovery would not be easy.

New Democracy’s leader Vangelis Meimarakis conceded defeat shortly after the exit poll figures were announced, offering his congratulations to Tsipras.

Conservative New Democracy followed second with 28.29%, proving wrong pre-election opinion polls that suggested it would challenge SYRIZA for the first spot.

Alexis Tsipras, who by any standard has had a hard year, is enjoying a moment of real triumph today after his radical-left Syriza party was returned to power in Greece. Extremist far-right party Golden Dawn came in third with 7%.

Creditors are expected to review progress of reforms as part of the bailout next month, while the government will also have to draft the 2016 state budget.

This gives the two men the opportunity to form again the coalition that governed Greece between January and September this year.
