Solution:
Russia's two influential political parties are the Union of Right Forces and the Liberal Yabloko Movement, that agreed to unite their organisations into a strong right-wing coalition.This is a case of political parties sharing power. Citizens must be free to select among many candidates for office in a democracy. In modern democracies, this manifests as rivalry between various parties. This way, it is ensured that power does not reside with only one. Over time, several political parties that represent different ideologies and social groupings also share power to get authority.
