My tribute to Benny Hill. A politician (from Greek "polis") is an individual who is involved in influencing public decision making through the influence of politics or a person who influences the way a society is governed through an understanding of political power and group dynamics. This includes people who hold decision-making positions in government, and people who seek those positions, whether by means of election, coup d'état, appointment, electoral fraud, conquest, right of inheritance (see also: divine right) or other means. Politics are not limited to governance through public office. Political offices may also be held in corporations, and other entities that are governed by self-defined political processes.
A parliament is a legislature, especially in those countries whose system of government is based on the Westminster system modelled after that of the United Kingdom. The name is derived from the French parlement, the action of parler (to speak): a parlement is a talk, a discussion, hence a meeting (an assembly, a court) where people discuss matters. (Wikipedia)
