Many countries had their worst showing in more than a decade in an index released on Tuesday that serves as a barometer of public sector corruption worldwide, from leading powers such as the US and France to authoritarian nations such as Russia and Venezuela.

Transparency International, which compiles the annual Corruption Perceptions Index, found that 47 countries out of the 180 it surveyed had their lowest score last year since it started using its current methodology for its global ranking in 2012. It said of its 2024 survey that “global corruption levels remain alarmingly high, with efforts to reduce them faltering”.
