The term "corrupt politician" refers to an individual who engages in dishonest or unethical behavior while holding a position of power within government. This can include activities such as accepting bribes, misusing public funds, abusing their authority for personal gain, and other forms of corruption that undermine the integrity of democratic institutions. The phrase is often used to describe individuals who have betrayed the trust placed in them by voters or citizens, and whose actions harm the interests of society as a whole.
