Most cantons use the system of proportional representation for National Council elections. The system of proportional representation is based on the submission of lists of candidates. At the end of the vote, mandates are allocated to each list in proportion to the number of votes obtained. Only after the number of mandates available to the list has been established will the distribution of seats to the candidates on the list take place. The candidates with the most votes on a list will be elected.
In two cantons, elections to the Council of States also held using the system of proportional representation (NE, JU).
