The **National Anti-Corruption Bureau of Ukraine (NABU)** is a specialized law enforcement agency established to combat high-level corruption in Ukraine. It was created in 2015 following the adoption of the Law “On the National Anti-Corruption Bureau of Ukraine” in 2014, as part of Ukraine’s commitments to the European Union to address systemic corruption and facilitate EU integration[2][4]. NABU’s main mission is to prevent, detect, investigate, and expose corruption crimes committed by top officials, including former presidents, members of parliament, government ministers, and heads of key state institutions[4]. NABU operates with investigative powers but does not have prosecutorial authority; it prepares cases for prosecution which are then handled by the Specialized Anti-Corruption Prosecutor’s Office (SAPO)[2]. The bureau initially started with about 70 detectives and is planned to grow to an authorized staff of 700. Its funding is supported by the Ukrainian government alongside international aid from the United States and the European Union, and it cooperates internationally, including an evidence-sharing agreement with the FBI[2]. Key functions of NABU include conducting pre-trial investigations, carrying out police operations, searching and arresting corrupt assets, safeguarding evidence, and ensuring confidentiality for whistleblowers[2]. The agency also engages in informational and analytical work and reports regularly to the public to maintain transparency[2][4]. NABU has played a critical role in Ukraine’s anti-corruption framework alongside other institutions like the National Agency on Corruption Prevention and the High Anti-Corruption Court, forming an integrated system to address corruption at the highest levels[5]. Since its inception, NABU has contributed to the exposure and investigation of numerous corruption cases involving senior officials, helping to raise public awareness and trust in Ukraine’s institutional reforms[10]. Notably, NABU is recognized for its institutional independence and is subject to annual independent audits to assess its effectiveness and operational autonomy, reinforcing it
