The 2012 Corruption Perception Index (CPI) ranks the UK at 17th, with a score of 74 out of a possible 100 (on a scale of 0 for most corrupt to 100 for least corrupt). TI said a continuing stream of political scandals prevented the UK from improving its position further, but said it should aim to be in the top 10. The UK ranks equal with Japan, and two thirds of the 176 countries rated score under 50. Denmark, New Zealand and Finland tie at the top of the index, scoring 90. The US is in 19th place, scoring 73. Afghanistan, North Korea and Somalia all score 8.
