"Mr. Modi, there is a southern deficit in your India calculus. The Hindi-belt image of your victory should not tighten itself into a North-South divide. Please appoint a deputy Prime Minister from the south, who is not a politician at all, but an expert social scientist, ecologist, economist or a demographer." Thus wrote Gopalkrishna Gandhi in an open letter to Narendra Modi after he had led the NDA to its massive win in May 2014.
