Corruption is a form of dishonest or unethical conduct by a person entrusted with a position of authority, often to acquire personal benefit. Corruption may include many activities including bribery and embezzlement, though it may also involve practices that are legal in many countries. Government, or 'political', corruption occurs when an office-holder or other governmental employee acts in an official capacity for personal gain. Stephen D. Morris, a professor of politics, writes that [political] corruption is the illegitimate use of public power to benefit a private interest.
