Greece's parliament voted on Thursday for an inquiry into claims the previous Socialist government inflated 2009 public deficit figures, a step that could put the reliability of the country's data back in the spotlight just days after it won a new bailout.
The upwards revision of Greece's budget deficit in 2009 to 15.4 percent of gross domestic product exposed to its euro zone partners the scale of its fiscal derailment and fuelled the debt crisis, raising fears over the fate of the euro currency union.
While Tuesday's agreement in Brussels on a 130 billion euro rescue package averts for now the threat of a chaotic default, it came only after the 17-nation euro zone sought unprecedented surveillance measures over Greece's budget practices.
In September, a board member of Greece's ELSTAT statistics body accused its chief Andreas Georgiou of inflating the public deficit data under pressure from the then Socialist government, which was seeking to justify harsh new austerity measures.
While the EU's own Eurostat statistical agency has since said the deficit was calculated in accordance with its standards, the affair has become a political hot potato between the two parties in Greece's ruling coalition.
Now is the time to clarify things, Finance Minister Evangelos Venizelos told the assembly before his Socialist PASOK party used its majority to launch the investigation with a late-night 168-76 vote in favor.
In a saga rich in irony, the conservative New Democracy (ND) party, which before entering the new ruling coalition last November had accused PASOK of complicity in inflating the data, unsuccessfully argued in parliament that the inquiry should be delayed until after elections scheduled for April.
New Democracy lawmakers suspect PASOK is keen to launch the inquiry because it can use its majority in parliament and the investigation committee to secure a favorable outcome - a charge firmly denied by PASOK.
Calls for an inquiry made headlines last year and PASOK might otherwise face an investigation later when it might not have a majority.
There is no logic to the New Democracy stance, PASOK deputy Theodora Tzakri told Reuters. They voted for the bailout and now they are not voting for the investigating committee.
The parliamentary inquiry is due to start in coming days and be concluded by the end of March.
Surveys show PASOK and New Democracy have both lost voters thanks to the tough budget cuts agreed in return for the EU/IMF bailout. But New Democracy is hopeful it can end up the leading party after an April election and so occupy the prime minister post currently held by the technocrat Lucas Papademos.
Georgiou's accusation last year was all the more astonishing to euro zone partners who had until then had to deal with Greece's frequent downwards revisions of its deficit totals.
In stark contrast, the 2009 deficit was projected early that year at 4.4 percent under the New Democracy government then in power, was briefly revised upwards to six percent and finally forecast at nine percent before elections in October that year.
After PASOK party's vote victory, the deficit was first revised up to 13.6 percent and finally 15.4 percent.
Georgiou, a veteran IMF statistician, already faces a criminal investigation over the allegations but no charges have been pressed against him. He denies any wrongdoing and has retained his post.
