What is Member: Definition and 227 Discussions

A member of parliament (MP) is the representative of the people who live in their constituency. In many countries with bicameral parliaments, this category includes specifically members of the lower house, as upper houses often have a different title. Member of Congress or Deputy is an equivalent term in other jurisdictions. Another term is Parliamentarian.
Members of parliament seem to tend to form parliamentary groups (also called parliamentary parties) with members of the same political party.

    Zero-force members prevent a truss from becoming a mechanism -- Why?
