The voting system
Each voter has one vote in the Mansfield constituency. The candidate with the most votes becomes the MP for that area. This voting system is called first past the post.
Usually, the political party with the most MPs then forms the government. However, two or more parties with a combined majority of MPs may form a coalition government.
