Sir: National Agricultural Research Centre (NARC) is an internationally recognised research institution. It has been established and modernised in 40 years with continuous assistance from the UN and friendly countries. Visionary progressive governments patronise and fund such research institutions for continuous improvement. Reportedly, some greedy politicians and bureaucrats are persuading the Prime Minister (PM) to let them shift NARC to oblivion and grab its 1,400 acres research farmland to convert it into a housing scheme for quick money. I wish to point out to the PM that there is no dearth of houses and plots if the Capital Development Authority is made functional to develop housing sectors awaiting development for years, vacate about 2,000 residential units in non-conforming use in compliance with court orders, and regulate the land of reportedly 105 illegal housing societies operating in Islamabad.With all sincerity, I appeal to the worthy PM to please beware of those greedy politicians and bureaucrats, who are bent upon causing immense damage to the credibility and vision of the PML-N government.M AKRAM NIAZIRawalpindi Cantt
