It is not possible to fight against corruption by legislative changes and forming various governmental councils. Serious structural changes and institutional reforms are necessary. Varujan Hoktanyan, Project Director of Transparency International Anti-Corruption Center, said this during the press conference at Media Center on January 25. Varujan Hoktanyan presented the results of Corruption Perceptions Index (CPI) 2016 of Transparency International global anti-corruption organization (TI). Since 1995, during 22 consecutive years, TI publishes the CPI, representing the perception of corruption in the public sector, based on expert assessments and opinion surveys. "We are talking about the public perception of corruption in the public system. The research is based on assessments of businessmen and experts and surveys," Hoktanyan said.
