The government is a coalition of right wing nationalists and left wing - nationalistic - marxists. Not sure why this should be called a left wing government. Calling the government left-wing is marketing to get sympathies with leftist people in Europe.
So I'd rather call the government nationalistic populist.
However, what's written seems not far from truth. Other sources have been reporting how Greece is running out of cash.

And now, with "finance ministry officials are categorically denying any suggestion that Greek representatives said the country would run out of cash" I think could be confirmed that Greece is running out of cash. http://www.theguardian.com/business/live/2015/apr/02/greece-...
