T'Puram: NSS general secretary G Sukumaran Nair said that Chief Minister Pinarayi Vijayan is speaking with an air of arrogance on Women Wall issue. Speaking to media, he opined that the women wall will split people based on caste and create sectarianism. Is it possible to implement renaissance movement only for women? Even though NSS is against women wall, the association hasn’t instructed anyone against participating in the wall, he said.
