Serbia has regressed on the Transparency International's Corruption Perceptions Index (CPI) annual ranking and now takes 86th place, Transparency Serbia organization stated Thursday.

Serbia marked a drop in CPI from 3.5 in the past two years to 3.3 in 2011, the annual report of Transparency International reads. Serbia ranked 78th in CPI rankings in 2010.

According to Transparency Serbia, the country's main problems are insufficient judicial reforms, violation of anti-corruption laws, influence of political parties on the work of the public sector, non-transparent decision-making processes, unnecessary procedures and insufficient capacities of bodies supervising the implementation of laws.

Out of all former Yugoslav countries, the highest ranked is Slovenia, which takes 35th place with 5.9 score. Croatia and Montenegro share the 66th place, Macedonia is 69th, whereas Bosnia-Herzegovina ranks lower than Serbia and takes 91th place with a score of 3.2.

Transparency Serbia President Vladimir Goati pointed out that a high degree of corruption disables economic development, adding that it is precisely the countries with a low CPI that have endemic corruption.

Goati told a news conference that the only good news is that Serbia has the same CPI as one EU member state - Bulgaria. In 2011, CPI ranked 183 countries on a scale of 0 - 10, where 0 means that a country is perceived as highly corrupt and 10 means that a country is perceived as very clean.
