Amaravati/New Delhi March 24: BJP President Amit Shah unleashed a belligerent attack on Andhra Pradesh Chief Minister N. Chandrababu idu, saying his “unilateral” decision to quit the NDA was for political considerations and not development, triggering a bitter war of words between the two on Saturday. idu hit back at Shah’s open letter to him, saying it was “full of false information” that hurt the sentiments of the Telugu people. The BJP chief’s March 23-dated letter formalised the split between the two allies, a week after the TDP pulled out of the NDA over the demands for special category status for Andhra Pradesh. Shah described as “untrue and baseless” the TDP chief’s allegations that the BJP was not sensitive to the aspirations of the people of Andhra Pradesh. He said the central government had released Rs 1,050 crore in the first three years coming to power as special development assistance for seven backward districts of the state.
