What do we mean by challenge of expansion?
The challenge of expansion involves applying the basic principle of democratic government across all the regions, different social groups and various institutions. Greater power should be given to local governments. Federal principles have to be extended to all the units of the federation. Women and minority groups should be include in the decision-making process. That is less and less decisions should remain outside the arena of democratic control. Most countries including India and other democracies like the US face this challenge.
