Answer:
referendum election.
Step-by-step explanation:
A referendum election is a kind of election that involves a large number of people living in a particular region or society. A referendum election is being used to know the opinions of that particular society which is then used in decision making. A popular example of referendum election is the BREXIT of the United Kingdom.
Please note that the normal Political election is somewhat different from referendum election because in referendum election one is only allowed to accept or reject a proposal and this may even lead to the amendment of the Constitution or can even lead to the use of new Constitution while the ''normal" election is where voters vote to put politicians into political offices.
