In most electoral systems, political parties, candidates and interest groups are required to register. In some systems, a candidate cannot run for office as an independent and must be affiliated with a registered party. Registration helps make the electoral process more transparent and holds these political entities accountable by requiring them to provide information on their activities and funding. Registration procedures and requirements may become integrity issues if they are used to exclude particular parties or players from the election process.
