Preselection is the process by which a candidate is selected, usually by a political party, to contest an election for political office. It is also referred to as candidate selection. It is a fundamental function of political parties. In countries that adopt Westminster-style responsible government, preselection is also the first step on the path to a position in the executive. The selected candidate is commonly referred to as the party's endorsed candidate.
