The Indian Independence Act 1947 [1947 CHAPTER 30 10 and 11 Geo 6] is an Act of the Parliament of the United Kingdom that partitioned British India into the two new independent dominions of India and Pakistan. The Act received Royal Assent on 18 July 1947 and thus modern-day India and Pakistan, comprising west (modern day Pakistan) and east (modern day Bangladesh) regions, came into being on 15 August. The legislature representatives of the Indian National Congress, the Muslim League, and the Sikh community came to an agreement with Lord Mountbatten on what has come to be known as the 3 June Plan or Mountbatten Plan. This plan was the last plan for independence.
