The 1946 general election was won by the Bengal Provincial Muslim League . The League received its largest mandate in Bengal , compared to smaller mandates in other Muslim majority provinces in India . The result was interpreted as an equivocal approval of the Pakistan movement . Suhrawardy was appointed prime minister . Suhrawardy 's frosty relations with Jinnah affected his ambitions of achieving a United Bengal , though both men wanted Calcutta to remain within an undivided Bengal . The Noakhali riots and the violence of Direct Action Day contributed to the government 's stand on partitioning Bengal . Despite support from Bengali Hindu leaders like Sarat Chandra Bose and the Governor of Bengal , Suhrawardy 's proposals were not heeded by Earl Mountbatten and Nehru . The Hindu Mahasabha 's legislators in the assembly demanded the partition of Bengal
