Vietnam is holding elections in single party system. In India, we have multi party system but there is move to chan ge to Congress Mukta Bharat- which would make us also a single party democracy. So it appears that there are many types of democracies. Multi party, three party, two party, single party. India was also for many decades after independence virtually single party democracy under congress.
In Vietnam, the voters will be exercising their rights. But the candidates will be only from one party and independents. Is this one party system democracy?
