Alexis Tsipras said yesterday he would revive Greece’s banks and its crippled economy, while demanding debt relief from creditors in his “first big battle” following an unexpectedly clear election victory that returned him to office as prime minister.

Preparing to be sworn in for a second term, he set those priorities at the top of a dauntingly long “to do” list that also includes implementing austerity polices and dealing with waves of migrants landing on Greek shores.

In Sunday’s election, voters gave Tsipras and his Syriza party a second chance to tackle Greece’s problems, and with it the benefit of the doubt over a dramatic summer U-turn, when he ditched his anti-austerity platform to secure a new bailout and avert ‘Grexit’ – a Greek exit form the eurozone.

His immediate objective would be the full restoration of stability in the economy and Greek banks, a Syriza official quoted Tsipras as telling party officials yesterday. The banks were shut for three weeks and the wider economy set back sharply in July before Tsipras caved in to accept austerity terms and an €86 billion bailout. The official said Tsipras had also announced that his “first crucial battle” would be securing debt relief.

Tsipras has promised to implement the tax increases, spending cuts and market reforms mandated by creditors under the bailout programme, which restrains much of his ability to set policy. But his party says there is still enough flexibility to cushion the impact on the most vulnerable Greeks.

Its election manifesto refers to “grey areas” in which details can still be adjusted, such as labour reforms – important in a still heavily unionised country – pension cuts, and plans to tackle the non-performing loans that have crippled banks. Creditors say that if Greece seeks to adjust the terms by easing austerity in one area it must tighten somewhere else.

Tsipras sees his first big battle as demanding debt relief from creditors

Syriza’s stronger-than-expected win secured it 145 of 300 parliamentary seats, meaning the party requires only one small coalition partner to form a government in Greece’s notoriously fractious legislature. It will govern with the same junior party it teamed up with in January, the once stridently anti-bailout right-wing Independent Greeks (Anel), which won 10 seats. Its leader Panos Kammenos said Tsipras would announce his Cabinet by tomorrow.

That alliance gives Tsipras more authority to steer the implementation of the bailout than he might have enjoyed with a broader coalition. He says his victory gives him a mandate for a full four-year-term, extraordinary in a country that has gone through five general elections in six years.

“This is a major personal triumph for Tsipras,” said political commentator Aristides Hatzis. “His political hegemony is unprecedented.”

But some analysts said creditors would have preferred Tsipras were restrained by a broader coalition, and that his stronger position would keep the threat alive of a future quarrel with the creditors – and even Grexit.

“Tsipras managed to convince a large part of the electorate that he was a tougher negotiator than previous governments,” said Mujtaba Rahman, of political risk consultancy Eurasia Group.

“The return of a second Syriza-ANEL government will concern Greece’s creditors ...[and we] maintain a 30 per cent risk of Grexit over the next two years.”

The big victory makes it easier for Tsipras to reinstate trusted members of the Cabinet that served during the often turbulent seven-month coalition he formed after his first election win in January.
