The world's most corrupt countries ranked

Transparency International's Corruption Perception Index 2014.

Somalia and North Korea are tied as the worlds most corrupt countries, according to a survey released by Transparency International.

The Corruption Perceptions Index 2014 is based upon "expert opinion" and measures the "perceived levels of public sector corruption".

"A poor score is likely a sign of widespread bribery, lack of punishment for corruption and public institutions that don’t respond to citizens’ needs," writes the survey's authors.

Countries that are the least corrupt are Denmark at number one and New Zealand at number two respectively.

Canada ranked 10th with Australia just below it at 11th. The USA was 17th.
