Corruption is a major concern all over the world. More research should be done to identify factors that may contribute to the effectiveness of corruption control. The purpose of this study is to look into the impact of law enforcement, incentives, and opportunities on the success of the anti-corruption programme in Malaysian government institutions. Questionnaires were provided to law enforcement agencies Department A, B, C and D. Based on the Fraud Triangle, a regression model was utilised to assess the relationship between law enforcement, motive, and opportunity, as well as the effectiveness of corruption control. The findings revealed that law enforcement and incentives have a major impact on the effectiveness of anti-corruption efforts. The findings could be used by the Malaysian Anti-Corruption Commission as guideline in the fight against corruption. Future research may be done longitudinally and cross-country. Second, in addition to surveys, other techniques of data collecting should include interviewing and observation. Third, a more comprehensive and larger sample size may be used.
