In this system, the government is responsible to the parliament, and the parliament is accountable to the people.

India was under British rule for almost 200 years. During this period, the British established a parliamentary system of government in India. The Indian National Congress, which was formed in 1885, also adopted the parliamentary form of government as its model. After independence, India adopted the same system and adopted a constitution that established a parliamentary democracy.
