The All-India Muslim League and the Indian National Congress were the two largest political parties in the Constituent Assembly of India in the 1940s. The Muslim League had demanded since its 1940 Lahore Resolution for the Muslim-majority areas of India in the northwest and the east to be constituted as 'independent states'. The 1946 Cabinet Mission to India for planning of the transfer of power from the British Raj to the Indian leadership proposed a three-tier structure: a centre, groups of provinces and provinces. The "groups of provinces" were meant to accommodate the Muslim League's demand. Both the Muslim League and the Congress in principle accepted the Cabinet Mission's plan. However, the Muslim League suspected the Congress's acceptance to be insincere.
