Negating talk of caste playing a role in the BJP not going beyond 240 in the Lok Sabha elections, Union Environment Minister Bhupender Yadav has said the Congress is indulging in politics of polarisation while ignoring affirmative action. Mr Yadav was speaking exclusively to NDTV at the 'Sustainability Mission' conclave on Friday. On the Congress and the opposition's demand for a caste census and how it could affect the upcoming Assembly elections, including Maharashtra, Haryana and Jammu and Kashmir, Mr Yadav said all societies have some form of division and if it is not caste, it could be class, religion or race; and the thing that matters is what is done about that.
