West Bengal Chief Minister Mamata Banerjee has taken strong exception to a glaring error in a Niti Aayog report, where Bihar was shown in place of West Bengal on a map meant to represent the state. In a sharply worded letter addressed to the Vice Chairperson of Niti Aayog, Mamata Banerjee expressed “deep concern and unequivocal disapproval” over the mistake, calling it “a grave lapse” and “an affront to the identity and dignity of the State of West Bengal.” The error appeared on the cover page of the “Summary Report for the State of West Bengal,” published on Niti Aayog’s official website.
