Giorgos Papaconstantinou is a Greek economist, former Minister for the Environment, Energy and Climate Change of Greece (2011-2012) and former Minister for Finance (2009-2011) with PASOK. As Finance Minister, in 2009 he presented a national deficit that was much larger than what was reported by the previous government, which led to Greece being shut out of international markets. During his tenure, Greece concluded its first loan agreement with the Troika (European Commission, European Central Bank, International Monetary Fund). He carried out the negotiations between the Greek government and its partners and undertook the implementation of severe austerity measures in Greece.
