What Types of MPs in parliament?

In parliament, there are typically three main types of Members of Parliament (MPs): constituency MPs, who represent specific geographic areas and are elected by local voters; list MPs, who are elected from party lists in proportional representation systems, representing broader party interests rather than specific regions; and senators or upper house MPs, who may serve different roles in bicameral systems, often focusing on broader legislative review. Each type has distinct responsibilities, contributing to the legislative process and representation of citizens.
