Greece faces criticism, as 'plan B' speculation mounts

Like the rest of Alexis Tsipras’ Syriza-led government, Varoufakis is new to government office, and he was, according to a report by Bloomberg, accused by one minister of being a "time waster and an amateur" during fractious exchanges in Latvian-capital Riga.

The meeting broke up without agreement on an economic reform package that would allow any of the remaining €7.2 billion of Greece’s bailout programme to be paid out.

Friday’s failure makes reaching a deal when finance ministers will next meet on 11 May imperative if Greece is to avoid running out of money. Tsipras appears to be pinning his hopes on brokering a personal agreement with German chancellor Angela Merkel.

But after nearly three months of unsuccessful talks, speculation about whether eurozone partners are preparing for a Greek exit from the eurozone is mounting.

Asked whether there was a plan B, Schaeuble said: "If a responsible member of the Eurogroup, or any responsible politician, were to answer this question with ’yes,’ we know what would happen. If he answered it with ’no,’ which I have done here by not even accepting the question, then we know that you won’t believe me."

Slovenian finance chief Dusan Mramor raised the possibility of a plan B during the meeting itself.

But Syriza parliamentary spokesman Nikos Filis attributed the eurozone’s hostility to fear of Syriza’s anti-austerity platform in remarks on Sunday.

“The issue is essentially political. It’s not only limited to an economic negotiation,” he said. “They don’t want the new Greek government, it doesn’t suit them. They’ve said it openly.”

Meanwhile, eurozone commissioner Valdis Dombrovskis told Germany’s Handelsblatt that the Commission will revise down its growth forecast for Greece this year.

"In winter we expected growth in Greece this year of 2.5 percent. Our spring forecast for Greece will turn out to be more pessimistic," Dombrovskis said.

The Greek treasury expects the country’s economy to grow by 1.4 percent in 2015 - down from its previous forecast of 2.9 percent.

Both Varoufakis and Tsipras’ government as a whole continue to enjoy strong public support, although a majority of Greeks would prefer to strike an agreement that allows it to remain in the eurozone.

Surveys over the weekend suggested that 55 percent of Greeks supported Varoufakis’ stance. However, a Kapa research poll published in the Sunday Vima newspaper showed that 72 percent wanted Greece to strike a deal with its creditors.

For his part, Defence minister Panos Kammenos warned that Greece could be forced to call a referendum if the crisis deepened, telling Mega TV that “in the event that they try to enforce an informal exit on us, a plebiscite could happen”.
