Iraq, Haiti, Myanmar and Guinea are ranked as the most corrupt countries in the world according to a new survey by Berlin-based corruption watchdog Transparency International.
The survey ranks 163 countries based on perceived levels of corruption among public officials and politicians in its 2006 Corruption Perceptions Index (CPI).
Haiti, the poorest country in the Americas, was ranked last, just below Iraq, Myanmar and Guinea.
TI noted several countries had a significant worsening of their ratings, including Brazil, Cuba, Israel, Jordan, Laos, Seychelles, Trinidad and Tobago, Tunisia and the United States.
