Little progress has been made in anti-corruption in the last 10 years, including in high income countries, and there has even been significant backsliding.
Many well-meaning anti-corruption efforts have failed, and some have even become corrupt. Research, including by SOAS, has found national anti-corruption agencies have become instruments for going after opposition leaders, or anti-corruption laws are implemented only selectively.
The reason: many policies fail to address ‘who will implement the rules?’, and — more importantly — ‘do they have sufficient interest or power to do so?’ Essentially, enforcement is too often ignored.
