A parliamentary constituency is a designated area from which a member of parliament (MP) is elected to represent the interests of the people living there. Each constituency has a specific geographical boundary, ensuring that every citizen has a voice in the legislative process. The number of constituencies can vary by country, depending on its population and political structure. In many democratic nations, such as India and the United Kingdom, parliamentary constituencies play a crucial role in elections. Voters in each constituency cast their ballots for candidates, and the candidate with the most votes becomes the MP for that area, responsible for addressing local and national issues.
