According to CBI sources, two lobbies—one represented by M. Sambasiva Rao, Indian agent of the dubious Turkey-based company, Karsan, and the other by Prakash Yadav, son of former fertiliser minister Ram Lakhan Singh Yadav—were working simultaneously in getting the deal through. Sambasiva and Sanjeeva Rao, brother-in-law of Narasimha Rao's second son Rajeshwar Rao, knew each other since college days. Sanjeeva, because of his proximity to the then prime minister, had a lot of clout in government undertakings. He introduced Sambasiva to C.K. Ramakrishnan, managing director of National Fertilisers Limited (NFL) and, along with Yadav, pressured him to clear the deal.
