Proportional representation is an electoral system designed to reflect the overall public support for political parties, ensuring minority groups can gain representation. The party-list system, a variant of proportional representation, allows voters to select a list of candidates from a party, with the allocation of seats determined by the party's share of the vote through various electoral rules. While this system simplifies voting and ensures proportionality, it has been criticized for undermining voter choice and concentrating power within party leadership.
