The National Common Voters' Roll refers to a comprehensive list of all eligible voters in a country. It is a database that contains the names, addresses, and other relevant information of individuals who are registered to vote in national elections. The roll is maintained by the election commission or a similar government body responsible for conducting elections. The purpose of the National Common Voters' Roll is to ensure transparency, accuracy, and fairness in the electoral process by providing a standardized and up-to-date list of eligible voters. It allows election officials to verify the identity of voters, prevent fraud, and ensure that every eligible citizen has the opportunity to exercise their right to vote.
