Brussels: No plans being made for Greek default

"The decisions taken by the extraordinary meeting of the Greek cabinet reinforce and restate the commitment of the Greek authorities to meet all the agreed targets," he said. "This is the essence of the conditionality that is attached to the financial assistance of the euro area and the IMF".

Asked whether the commission was working on a default scenario, Altafaj-Tardio said: "We are not working on such a hypothesis."

On Sunday, Der Spiegel reported that Germany's finance ministry is exploring Greek default scenarios, including a possible disorderly unwinding of its debt obligations.

As European markets tumbled on the back of the rumors, the German government on Monday attempted to undo some of the damage caused by the report, as well as comments from senior officials that appeared to suggest the country was preparing for the worst case scenario of Greece leaving the euro.

Economy minister Philip Roesler insisted that Germany does not want to expel the heavily indebted nation.

"Our common goal is the stability of the euro and we want Greece to stay in the euro," he said. Two days ago, Roesler said that an orderly default of the country is no longer taboo.

Government spokesman Steffen Seibert backed Greece's efforts. Berlin "assumes that Greece is doing everything it can" he said.

"Our goal is quite clear: We want to stabilise the eurozone as a whole," he added.

However, Seibert also warned: "Our line on Greece is clear: We will help, but only under strict conditions."

If the country does not meet the demands of international lenders, "then the next tranche cannot be paid. That is quasi-automatic," he continued.

Altafaj-Tardio said that he expects officials from the troika - the commission, the European Central Bank and the International Monetary Fund - to return to Athens this week, although he could not offer a specific date. He added the review mission is likely to complete its work by the end of the month.

Last week, troika inspectors abruptly ended their mission to the country. The reason given for their sudden departure was that the country had more technical work to do, but speculation mounted that the government was not meeting its targets

"A time-out was decided by both parts. There was important progress in the last days. Therefore the troika can resume its work," he continued.

He said that once the review mission is complete the EU and IMF will hand over the latest chunk of bailout cash: "This will allow the euro area and IMF to take the necessary decision to release the sixth tranche."
