context: Greece was accused of trying to cover up the extent of its massive budget deficit in the wake of the global financial crisis. The allegation was prompted by the massive revision of the 2009 budget deficit forecast by the new PASOK government elected in October 2009, from "6–8%" (estimated by the previous New Democracy government) to 12.7% (later revised to 15.7%). However, the accuracy of the revised figures has also been questioned, and in February 2012 the Hellenic Parliament voted in favor of an official investigation following accusations by a former member of the Hellenic Statistical Authority that the deficit had been artificially inflated in order to justify harsher austerity measures.
