Minor party is a political party that plays a smaller (in some cases much smaller, even insignificant in comparison) role than a major party in a country's politics and elections. The difference between minor and major parties can be so big that the membership total, donations, and the candidates that they are able to produce or attract are very distinct. Some of the minor parties play almost no role in a country's politics because of their low recognition, vote and donations. Minor parties often receive very small numbers of votes at an election (to the point of losing any candidate nomination deposit.) The method of voting can also assist or hinder a minor party's chances. For example, in an election for more than one member, the proportional representation method of voting can be advantageous to a minor party as can preference allocation from one or both of the major parties.
