	Transparency International in its annual Corruption Perceptions Index for 2010 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. However, 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.
