The election for the Belgian Chamber of Representatives is based on a system of open list proportional representation. Several months before an election, each party forms a list of candidates for each district. Parties are allowed to place as many candidates on their lists as there are seats available. The formation of the list is an internal process that varies with each party. The place on the list is considered to play a role in the election of a candidate, by giving stronger visibility to those high on the list; this phenomenon, however, seems to have lost importance since the last electoral reform.
