ATHENS: Greek elections will be held on June 17, the Athens News Agency said on Wednesday, adding that a senior judge had been tasked with heading a caretaker government to organise the ballot.

Council of State president Panagiotis Pikrammenos, the head of Greece's top administrative court, will be named as caretaker prime minister, the semi-state ANA said.

Political leaders agreed on the appointment with President Carolos Papoulias after an inconclusive general election on May 6 which delivered a strong anti-austerity message and raised fears of a Greek eurozone exit.

Nine days of talks on forming an emergency coalition had failed but there is no guarantee that the new vote will produce a viable government.

The radical leftist Syriza party, chief opponent of a massive EU-IMF bailout accord, is tipped to win, meaning yet more uncertainty over Greece's future in the single currency club for some time to come.
