The report summarises the results from the assessment of the anti-corruption policy implementation in nine public organisations, that exert governance, regulatory or control functions in three preselected economic sectors (construction, wholesale of fuels, and wholesale of pharmaceuticals) in Bulgaria, Italy, Romania and Spain. The assessments evaluate the implementability, implementation, effectiveness and risk coverage of anti-corruption measures and policies on the level of individual public institution. Its aim is to monitor and facilitate the enforcement of these policies and to provide concrete advice to the institution’s management on improving their anti-corruption setup. The assessment applied an innovative methodology (MACPI), which has already been successfully implemented in a number of public organisations across Europe.
