Why did the Congress accept the Mountbatten Plan?

The Congress finally accepted the Mountbatten Plan because of the following reasons-

1. The large-scale communal riots that engulfed the whole country convinced all that the only solution to the communal problem lay in the Partition of India.
2. The League had joined the Interim Government to obstruct and not to cooperate. Experience of working with the League had convinced the Congress that it could not have a joint administration with the League.
3. 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 weak Centre.
4. Any further continuation of British rule would mean a greater calamity for India. The British were instigating the rulers of the Indian States to remain independent. Hence, partition was the price for immediate independence.
5. The 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 rid the Constitution of separate electorates and other undemocratic procedures. India could then evolve as a truly secular and democratic polity.
