Corruption affects all member countries of the European Union and costs the bloc's economies about 120 billion euros ($162.19 billion) a year, an official EU report published Monday said.

European Commissioner Cecilia Malmstrom, who presided over the first-ever official EU-wide study on corruption, said the estimated amount lost annually due to padded government contracts, covert political financing, bribes to secure health care and other corrupt practices would be enough to fund the European Union's yearly operating budget.

All 28 EU member states suffer from some level of corruption — defined broadly by the report as the "abuse of power for private gain" — the report found.

"There are no corruption-free zones in Europe," Malmstrom said at a news conference. "We are not doing enough. And this is true for all member states."

Across Europe, 76 percent of people said they thought corruption was widespread in their own country. But in Greece, 99 percent of those polled said corruption was prevalent, with Italy (97 percent) and Lithuania, Spain and the Czech Republic (95 percent) right behind.

But when polled on whether they had been asked to or were expected to pay a bribe in the past year, Lithuanians came out ahead, with 29 percent of people reporting that they had been asked to pay bribes. Meanwhile, 7 percent in Greece, 8 percent in the Czech Republic and 2 percent in Italy said they had been asked to or were expected to pay a bribe in the past year.

Robert Barrington, of Transparency International UK, an anti-corruption organization, told Al Jazeera on Monday that the report was "sadly not surprising," adding that it showed that corruption was "not just a problem in emerging markets, but everywhere in the world."

The study did not rank countries according to the prevalence of corrupt practices, but Malmstrom acknowledged some of the "younger democracies" in Eastern Europe face special challenges.
