In politics, an independent or non-party politician is an individual not affiliated to any political party. Independents may hold a centrist viewpoint between those of major political parties, a viewpoint more extreme than any major party, or they may have a viewpoint based on issues that they do not feel that any major party addresses. Other independent politicians are associated with a political party and may be former members of it, but choose not to stand under its label. A third category of independents are those who may belong to or support a political party but believe they should not formally represent it and thus be subject to its policies. Finally, some independent candidates may form a political party for the purposes of running for public office.
