On February 20, 1947, British Prime Minister Clement Attlee announced that British rule in India would cease by June 30, 1948, after which power would be transferred to responsible Indian leaders. This announcement was met with heightened agitation from the Muslim League, which demanded the partition of the country. On June 3, 1947, the British Government clarified that any Constitution drafted by the Constituent Assembly (formed in 1946) would not be applicable in areas unwilling to accept it. On the same day, Lord Mountbatten, the Viceroy of India, proposed the partition plan, known as the Mountbatten Plan, which was accepted by both the Congress and the Muslim League. The plan was promptly enacted through the Indian Independence Act of 1947.
These provisions marked a pivotal moment in Indian history, culminating in the establishment of independent governance in India and Pakistan.
At the stroke of midnight on August 14-15, 1947, British rule officially ended, and power was transferred to the two newly independent Dominions of India and Pakistan. Lord Mountbatten became the first Governor-General of the Dominion of India, swearing in Jawaharlal Nehru as its first Prime Minister. The Constituent Assembly of India, formed in 1946, subsequently became the Parliament of the Indian Dominion.
