Greek impasse prompts euro exit warnings, rattles markets

ATHENS/ROME (Reuters) - With efforts to patch together a Greek government looking doomed, EU policymakers warned the country it could not remain in the euro zone if it ripped up its bailout programme, and financial markets ratcheted up the pressure on the bloc.

Eight days after inconclusive elections, Greece's political parties have failed to form a coalition and opinion polls show that anti-bailout parties would perform most strongly in a fresh vote which is likely next month.
