The self-declared architect of the world's biggest lift irrigation project Kaleshwaram, former Chief Minister K Chandrasekhar Rao, has told the PC Ghose Commission of Inquiry that while he envisioned the project and gave overall approval, all technical decisions were taken by engineers, sources said. KCR, as he is popularly known, is said to have told the one-man commission of former Supreme Court judge, Justice Pinaki Chandra Ghose, that he would not like to be examined in public. So only Justice PC Ghose and Commission secretary Muralidhar were present when he answered questions put to him by the Commission.
