This review analyses the Anti-corruption Policy of the State of Mexico and Municipalities, highlighting its strengths (i.e. inclusion and rigour) as well as the need to include specific integrity risks (i.e. policy capture) to make it more comprehensive. The review analyses how the State Government could develop ownership of ethical rules and values to effectively influence public officials’ behaviour. It also assesses the internal control and risk management scheme of the State of Mexico, providing an overview of its good practices and weak points. Finally, it examines the role of the administrative liability regime for state public officials and its effectiveness in ensuring accountability. It describes the legal framework for administrative responsibilities, which provides a comprehensive and solid foundation for enforcing integrity rules and standards, but requires support to improve implementation.
