A two-day workshop on “Integrity testing and whistleblower protection within law enforcement internal controls” took place on 21–22 November 2016 in Kyiv, Ukraine.  Some 12 department officers from the Internal Control Department of the National Anti-Corruption Bureau of Ukraine (NABU) participated and benefited from the workshop, which was a combination of expert discussions and practical exercises. It offered the participants an opportunity to acquaint themselves with internal and managerial control tools such as integrity testing and work with whistleblowers. During the two-day workshop, Council of Europe experts shared good practices of countries including the United Kingdom, Slovenia and Romania. The workshop represents the second activity under the CoE/EU Eastern Partnership Programmatic Cooperation Framework Project “Fight against Corruption in Ukraine” targeted at supporting NABU’s efforts in strengthening internal control structures.
