Independent politician
In politics, an Independent is someone who is not a member of any political party. Independents can have a centrist opinion on what they want to do when they are elected, or they may have extreme opinions that are very different from what other parties have. Also, there are some politicians who may choose to contest an election by themselves as an Independent candidate even if they used to be a member of a political party, because they do not want to follow their party's political ideology. Some Independents may create their own political party just to take part in an election.
