"Just like the previous Congress-led UPA government, the NDA government is adopting the same discriminatory attitude while honouring two persons of the same caste - Vajpayee and Malviya - with the Bharat Ratna recently," she told a press conference here.
"Kanshi Ram should have been honoured keeping in mind his sacrifices and contribution. Similarly, Jyotiba Phule, who belonged to a backward caste, should have been given the award for his work in the field of education and efforts to establish equality in society," she said.
