Singapore is perceived to be the least corrupt country in Asia according to Transparency International's Corruption Perceptions Index (CPI) from 1995 to 2010. In 2010, Singapore was ranked joint first with Denmark and New Zealand among 178 countries on the CPI with a score of 9.3. However, this does not mean that corruption does not exist in Singapore, which has its share of corruption scandals too. Indeed, the scandal involving Teh Cheang Wan attracted a great deal of attention because he was the Minister for National Development in Singapore from 1979 to 1986.
