The Index, which ranks 180 countries and territories by their perceived levels of public sector corruption, according to experts and business leaders, uses a scale of 0 to 100, where 100 is the 'cleanest', and 0 is the 'most corrupt'.
New Zealand was the country assessed as being the least corrupt, with a score of 89. Somalia was the poorest performing country, achieving a score of just 9. Other countries in the top 10 include Denmark, Finland, Norway, Switzerland, Singapore, Sweden, Canada, Luxembourg, the Netherlands, the United Kingdom and Germany.
