Union Textiles Minister Smriti Irani on Tuesday launched a scathing attack on the Congress and the partys former president Sonia Gandhi, saying there was clear proof of a conspiracy to destroy BJP president Amit Shah. Addressing a press conference in New Delhi, Smriti Irani, referring to the Sohrabuddin encounter case, said the Congress used the CBI to frame Amit Shah. Irani claimed that the Sohrabuddin case was politically motivated. The entire investigation was carried out according to a set script to achieve certain goals. Truth has finally won in a case that was nothing but a conspiracy by Congress, she said.
