In this category links are available to articles on liberal parties. This includes both (free) market or classical liberal and social liberal parties, but the liberal-conservative parties are included in the sub-category liberal-conservative parties. Also parties in the progressive liberal tradition of 'Radicalism' are included, even when these parties wouldn't label themselves as liberal. The U.S. Democratic Party is included since it embraces a liberal wing, even in the European sense of the word. For more information, see here
