In March, 1947, Lord Mountbatten replaced Lord Wavell. He announced his plans on June 3, 1947. His earlier Plan Balkan was abondoned by this June 3, Plan. It offered a key to the political and constitutional dead lock created by the refusal of Muslim League to join the Constituent Assembly formed to frame the constitution of India. Mountbatten's formula was to divide India but retain maximum unity. The country would be partitioned but so would be Punjab and Bengal, so that the limited Pakistan that emerged would meet both the congress and the league's position to some extent. The league's position on Pakistan was conceded in that it would be created, but the congress position on unity would be taken into account to make Pakistan as small as possible. He laid down detailed principle for the partition of the country and speedy transfer of political powers in the form of dominion Status to the newly formed dominion of India and Pakistan. It's acceptance by the congress and the Muslim League resulted in the birth of Pakistan.
