Answer:
Reform (party).
Explanation:
As the exercise explains, a Reform Party is a minor party that bases its appeal on the claim that the major parties are having a corrupting influence on government and policy or claims that the population is disillusioned with the state of goverment and politics in general. Therefore, like in the United States, this type of parties are independent of the other parties, given that they aim to reform, to correct the system.
