What are the features of fptp …

In a first-past-the-post (FPTP or FPP; sometimes formally called single-member plurality voting or SMP) electoral system, voters cast their vote for a candidate of their choice, and the candidate who receives the most votes wins. FPTP is a plurality voting method, and is primarily used in systems that use single-member electoral divisions. FPTP is used as the primary form of allocating seats for legislative elections in about a third of the world's countries, mostly in the English-speaking world (the United States, the United Kingdom, Canada, India, Pakistan, and other countries in the Commonwealth of Nations).

Many countries use FPTP alongside proportional representation, for example, for special constituencies (e.g. for minorities or outlying areas) and/or as part of a mixed-member proportional representation system. It is also used to elect heads of state in Taiwan, Iceland, Mexico, and South Korea.

Countries that primarily use a first-past-the-post voting system for national legislative elections
FPTP can be used for single- and multiple-member electoral divisions. In a single-member election, the candidate with the highest number (but not necessarily a majority) of votes is elected. In a multiple-member election (or multiple-selection ballot), each voter casts (up to) the same number of votes as there are positions to be filled, and those elected are the highest-placed candidates corresponding to that number of positions. For example, if there are three vacancies, then voters cast up to three votes and the three candidates with the greatest number of votes are elected.
