As a result of the partition, under the Mountbatten plan, a separate Constituent Assembly of Pakistan was established on 3 June 1947. The representatives of the areas incorporated into Pakistan ceased to be members of the Constituent Assembly of India. New elections were held for the West Punjab and East Bengal (which became part of Pakistan, although East Bengal later seceded to become Bangladesh); the membership of the Constituent Assembly was 299 after the reorganization, and it met on 31 December 1947.
