The NDA Government at the Centre could have trouble on its hands with TDP leader Chandrababu Naidu sulking. The latest fracas is due to the delay on behalf of Finance Ministry in giving a recommendation to the World Bank, owing to which Andhra Pradesh may have to forego World Bank assistance to the tune of Rs 1,600 crore during the current financial year. Naidu's problem is that to get the funds from the World Bank, the Centre has to recommend or stand guarantee for the loan.
