It is not true that because of the British democracy came to India. Because of the British India was under colonial rule for many centuries. Also democracy existed in India much before the arrival of the British.

Another thing I would like to remind you is the British ruled countries like Nepal, Afghanistan, Pakistan all went the wrong way and they saw Military dictators and Kings rather than democaracy? Why?

But our leaders were impressed with democracy. May be that has influenced India.
