The prime minister of India is the head of government of the Republic of India. Executive authority is vested in the prime minister and his chosen Council of Ministers, despite the president of India being the nominal head of the executive. The prime minister has to be a member of one of the houses of bicameral Parliament of India, alongside heading the respective house. The prime minister and their cabinet are at all times responsible to the Lok Sabha.

The Indian National Congress (INC), colloquially the Congress Party or simply the Congress, is a political party in India with deep roots in most regions of India. Founded on 28 December 1885, it was the first modern nationalist movement to emerge in the British Empire in Asia and Africa. From the late 19th century, and especially after 1920, under the leadership of Mahatma Gandhi, the Congress became the principal leader of the Indian independence movement. The Congress led India to independence from the United Kingdom, and significantly influenced other anti-colonial nationalist movements in the British Empire.
