Claim: Sri Lanka has been ranked in the top four most corrupt nations in the world

Q1: Which Country is the most most corrupt nation globally?
A1: Alexander E.M. Hess, Michael Sauter  |  24/7 Wall Street

More than half of the world's population believes corruption in the public sector is a very serious problem. Liberia and Mongolia are the two most corrupt countries in the world, according to a recent study. In both countries, 86% of residents believe corruption in the public sector is a very serious problem. Residents in the vast majority of countries around the world believe corruption has only gotten worse in the past two years.

Anti-corruption nonprofit Transparency International has released its 2013 Global Corruption Barometer, which surveyed residents in 107 countries. The world's corrupt nations differ in many ways. Four are located in Africa, three in Latin America and two in Asia. These nations also vary considerably in size and population. Mongolia has just 3.2 million residents, while Mexico, Nigeria and Russia are three of the largest countries on the globe, each with more than 100 million people. Based on the percentage of surveyed residents that reported corruption in the public sector is a very serious problem, these are the world's most corrupt nations

Q2: Is Sri Lanka among the top four most corrupt nations in the world?
