A comparison of U4 partner agencies’ anti-corruption strategies shows that while they take different shapes, their purpose, content and approach is similar. Emphasis is placed on safeguarding donor funds and guiding support for anti-corruption interventions. They also signal a commitment to anti-corruption within the agency, to their domestic audience and partner countries. To go beyond mere rhetoric, strategies need to be properly resourced. Mainstreaming anti-corruption through other strategies and guidelines can potentially create greater integration. Comprehensive anti-corruption strategies run the risk of being viewed as separate from an agency’s overall work. Balancing risk management and zero tolerance in agency strategies emerges as a central issue.
