West Bengal Chief Minister Mamata Banerjee, in a letter addressed to Prime Minister Narendra Modi, has alleged that Aadhaar cards of people from Scheduled Caste, Scheduled Tribes and Other Backward Classes, have been deactivated in the state. She also termed the alleged move as a gross violation of natural justice.

The Trinamool supremo further alleged that the Aadhaar cards had been deactivated without any prior intimation to the members of the said community. 

"Every citizen in the state is in a state of fear about this matter. I would like to know from you about the causes for such a sudden action of deactivation of Aadhaar Cards without assigning reasons," Mamata Banerjee's letter read.

Further, she asked the Prime Minister if the alleged deactivation of Aadhaar cards in Bengal was a "sinister plot to deprive eligible beneficiaries of welfare schemes, conveniently timed before the Lok Sabha elections".
