Brussels - Greece's budget deficit surged to 3.5 per cent of gross domestic product (GDP) in 2007, according to revised figures published on Wednesday by the European Union's statistical office, Eurostat.
The figure is well above previous estimates and exceeds the 3-per cent limit by which countries which share the euro need to abide to.
The EU's executive arm, the European Commission, had earlier warned that it would open infringement procedures against Greece if its excessive deficit was confirmed.
However, national governments agree on the need to relax the strict rules governing the EU's Stability and Growth Pact in light of the "exceptional circumstances" resulting from the current financial crisis.
