Though the nationalists deplored the partition of India; the All-India Congress Committee finally accepted the Mountbatten Plan for the following reasons:
1. The whole country was engulfed with large-scale communal riots over the partition of India. The Congress was convinced that the only solution to the communal problem lay in the partition of India into India and Pakistan.
2. The experience of working with the Muslim league had convinced the Congress that the League had joined the Interim Government to obstruct and not to cooperate and that having a joint administration with the League was not feasible.
3. The Congress also understood that the only alternative to partition was a Federation with a weak centre. A smaller India with a strong central authority was better than a bigger State with a weak Centre.
4. The Congress got ready for partition as it would lead to immediate independence from the British because any further continuation of British rule would mean a greater calamity for India as the British were instigating the rulers of the Indian States to remain independent.
5. The Congress leaders felt that further delay in the transfer of power could find India in the midst of a Civil War.
6. The leaders felt that partition would evolve India as a truly secular and democratic polity as it would get rid of the Constitution of separate electorates and other undemocratic procedures.
