Abstract This analysis concerns the use of punitive actions to curb corruption. Propositions from the literature on corruption state that by prosecuting offenders for corruption‐related crimes and thus ending impunity, particularly among high‐level political figures (‘big fish’), a political culture of less corruption will evolve. This, however, hinges on there being no impunity and politicization of prosecutions. This study empirically assesses whether this condition holds in the sub‐Saharan African political context. A unique database on corruption‐related prosecutions at the level of ministers across Africa was compiled and patterns were found that suggest that prosecutions are indeed politicized and serve as a way to eliminate political rivals. These findings are a warning in the face of the international community's overly technical and apolitical approach to anti‐corruption in sub‐Saharan Africa.
