Prime Minister Narendra Modi on Wednesday lashed out at Bihar Chief Minister Nitish Kumar for his controversial remarks on the role of women’s education in population control and questioned the silence of the Opposition on the matter.

Addressing a rally in Madhya Pradesh’s Guna, PM Modi said such statements made against women amounted to insulting the country.

“A big leader of the INDI alliance, ‘Ghamandiya Gathbandhan’ used indecent language for women inside (Bihar) assembly yesterday. They are not ashamed.
