The Challenge of deepening of democracy is faced by every democracy in one form or another. This involves the strengthening of the institutions and practices of democracy. This should happen in such a way that people can realize their expectations of democracy. But ordinary people have different expectations from democracy in different societies.

This is an example of strengthening a particular political institution.
