Greek President Karolos Papoulias is due to meet party leaders to set up a caretaker government ahead of fresh elections expected next month.

希腊下个月大选举行之前，总统卡罗洛斯·帕普利亚斯将会见政党首脑建立临时政府。

A final round of talks to secure a coalition¹ failed on Tuesday raising new concerns over Greece's eurozone future.

There has been deadlock² since the 6 May election over whether to continue with the austerity measures required by an international bailout agreement.

The uncertainty³ pushed the euro to a new four-month low against the dollar.

EU officials fear the country will elect an anti-bailout government, which Brussels says could hasten Greece's exit from the euro.

That possibility is now discussed openly among Europe's leaders, and could threaten the very survival of the single currency, the BBC's Mark Lowen in Athens says.

Euro exit?

President Papoulias will meet all political leaders at 13:00 (10:00 GMT) on Wednesday and is expected to select a senior judge to take over the running of the country.

New elections are expected to take place on 10 or 17 June.

On Wednesday the eurozone crisis pushed Asian stocks lower and knocked oil prices.

Tokyo's Nikkei index dropped 1%, while Hong Kong's Hang Seng and South Korea's Kospi lost about 3%.

The euro fell more than half a cent to $1.27.

The uncertainty over the euro has also sparked concern over a run on the banks in Greece.

Greek newspapers report that around 700m euros have been withdrawn⁴ from high street banks over the past few days, the BBC's Richard Galpin in Athens says.

People are concerned that an exit from the eurozone and a reversion to the drachma（古希腊的银币名） would wipe out much of people's savings⁵, he says.

European leaders say they will cut off funding for Greece if it rejects the bailout agreed in March.

This would mean effective bankruptcy⁶ for Greece and its all but certain exit from the European single currency, analysts⁷ say.
