One of the BJP's top strategists, Ram Madhav, held an important meeting this morning on what has blown up as a huge dispute between the central government and the four large southern states. Ram Madhav met with NK Singh of his party; last year, Mr Singh, a former top bureaucrat, was named the head of the 15th Finance Commission. The controversy in which he is centrally placed lies in whether southern states like Tamil Nadu and Kerala will get a smaller share of tax revenue only because their population has decreased - an accomplishment for which they should be rewarded, not penalised.
