member of parliament

A member of parliament (MP) is a person elected or appointed to a parliament, often representing the people in a specific electoral district. Members of parliament typically form parliamentary groups, sometimes called caucuses, with members of the same political party. In many countries with bicameral parliaments, this term refers only to members of the lower house since upper house members often have a different title. The terms congressman (or congresswoman) and deputy are equivalent terms used in other jurisdictions.
