Some of the richest countries in the world – Finland, Denmark, New Zealand, Iceland, Singapore and Sweden – scored 9 or higher out of a clean score of 10 in the new Corruption Perceptions Index (CPI). But many of the world’s poorest countries scored less than five, suggesting high levels of perceived corruption in government and public administration.

The countries with a score of two or less are Azerbaijan, Bolivia, Cameroon, Kenya, Indonesia, Uganda, Nigeria and Bangladesh.

The CPI is published by Transparency International.
