Greece drew closer to holding repeat elections next month after Radical Left leader Alexis Tsipras said Wednesday he has failed to forge a coalition that would end the financially struggling country's political deadlock.

Tsipras, whose anti-austerity party was the surprise runner-up in weekend national elections, said that despite his best efforts since receiving the presidential mandate on Tuesday, he was unable to raise enough support to form a government.

Tsipras has been seeking support for a left-wing government that will reject the terms of Greece's international bailout — which critics say will lead the country out of the euro.

He was tasked with forming a government after first-placed conservative leader Antonis Samaras — who backs the country's international bailout terms — failed to do so within hours of getting the mandate on Monday.

Next in line is Socialist leader Evangelos Venizelos, Greece's former finance minister. If he also fails, the president will host party leaders in a last-ditch effort to avoid new elections next month.
