Ukraine is a country with wide scale and systemic corruption, which makes a crucial influence on the economic, political, social and other spheres of public life. The traditionally low scoring of Ukraine by the Corruption Perception Index of the “Transparency International” is the evidence of this. The plague of corruption has penetrated all levels of government and public institutions, starting from the highest-level public officials. All formal and informal institutions have become used to corruption and adapted to it, including law enforcement agencies.
