Political parties are necessary for modern democracies to function effectively. They perform key roles such as contesting elections, developing policy platforms, forming and running governments, providing opposition, and shaping public opinion. While many citizens are critical of political parties, levels of participation and identification with parties have been increasing in India over the past few decades according to surveys. Political parties do not command high levels of trust globally, but party membership and affiliation remains relatively strong in India compared to some advanced democracies.
