West Bengal CM Mamata Banerjee criticised Union Home Minister Amit Shah, saying that his remarks against BR Ambedkar were "derogatory" and insult to millions who look up to Babasaheb Ambedkar. "The mask has fallen!...Amit Shah chose to TARNISH this occasion," Banerjee wrote on X. "This is a display of BJP's CASTEIST and ANTI-DALIT mindset," Banerjee added.
