18 most corrupt countries in the world

Transparency International has published an annual Corruption Perceptions Index 2013 (CPI), which ranks countries and territories based on how corrupt than their administrative institutions and policy are perceived to be on a scale from 0 (highly corrupt) to 100 (very clean).

Crafted from a combination of surveys and assessments of "abuse of power for private gain", the CPI is the most widely used indicator of corruption worldwide.

Syria, in the midst of a brutal civil war, fell eight points in the last year, as government officials are taking advantage of the food crisis. Libya, in the midst of revolutionary turmoil, fell six points by defeating Iraq in official corruption.
