A political party is a political organization subscribing to a certain ideology or formed around very special issues with the aim to participate in power, usually by participating in elections.
The parties properly belong in separate articles under each nation. Election results for the parties can be found at List of election results or among the external links at the end of the article.
Included are the countries and entities listed in the list of sovereign states and the list of dependent territories (as far as these last have a form of self government).
