Amartya Sen has condemned the caste system still prevailing in India. The 82 year old Noble prize winning economist has said, "I would say caste is anti-national because it divides the nation. We want to be national, not anti-national, for which it is important to eliminate all divisions". He said this while addressing a special event at the London School of Economics (LSE) to mark the 125th birth anniversary of Dalit rights activist Babasaheb Bhimrao Ramji Ambedkar.
