This chapter examines the coherence and comprehensiveness of Mexico’s evolving public integrity system. In line with the principles of the OECD 2017 Recommendation on Public Integrity, it examines the recently reformed institutional arrangements for national and local anti-corruption systems with a view to further strengthening co-ordination and supporting the implementation of action plan initiatives at national and subnational levels. The chapter provides recommendations on supporting implementation through stronger monitoring and capacity building. Finally, the extent to which non-governmental stakeholders have been included is discussed. The chapter discusses how new reforms could be better mainstreamed across the whole of government, better served by the inclusion of additional stakeholders to reach target groups such as the private sector, and better supported by stronger senior leadership and resources to ensure effective implementation.
