What is the difference between the parliamentary and Soviet principles of organizing power?

When the parliament existed, power was divided. The parliament limited the power of the ruler of the country, participated in the creation of bills, and adopted them. He could also challenge the decisions of the monarch. Under Soviet rule, the government of the country was completely concentrated in the hands of one party, no one could dispute its decisions. Those who did not agree with the current policy were persecuted and repressed.
