In its Corruption Perceptions Index for 2010, Transparency International gave Saudi Arabia a score of 4.7 (on a scale from 0 to 10 where 0 is "highly corrupt" and 10 is "highly clean"). Saudi Arabia has undergone a process of political and social reform, such as to increase public transparency and good governance, but nepotism and patronage are widespread when doing business in the country; the enforcement of the anti-corruption laws is selective and public officials engage in corruption with impunity. A number of prominent Saudi Arabian princes, government ministers, and businesspeople, including Prince Al-Waleed bin Talal, were arrested in Saudi Arabia in November 2017.
