The plan announced by Viceroy Lord Mountbatten on 3 June 1947 (the "3rd June Plan") that set out the partition of British India into two dominions, India and Pakistan, and led to the Indian Independence Act, 1947.
- Announced on 3 June 1947 by Lord Mountbatten, the last Viceroy, and accepted by the Congress, the Muslim League, and the Sikhs.
- Provided for the partition of India into the two dominions of India and Pakistan, with both granted Dominion Status and the right to frame their own constitutions.
- Provided for the partition of Bengal and Punjab; a Boundary Commission under Sir Cyril Radcliffe was set up to draw the boundary (the Radcliffe Line).
- Gave princely states the choice to accede to India or Pakistan, or to remain independent (in practice they had to accede to one of the two).
- Was given legal effect by the Indian Independence Act, 1947, which set 15 August 1947 as the date for the transfer of power.
It is the immediate blueprint for Partition and independence, with the date (3 June 1947), the Radcliffe Line, and the Dominion arrangement all high-frequency facts.
The Mountbatten Plan (3 June 1947) granted Dominion Status, not republic status; India became a republic only on 26 January 1950 when the Constitution came into force.
3 June 1947 (Mountbatten Plan): partition into India and Pakistan as dominions; Radcliffe Line; enacted via the Indian Independence Act, 1947.
