PATNA: Sharpening its attack against the Narendra Modi government over alleged “secret deal” in purchase of Rafale fighter aircrafts, the Congress on Wednesday asked why the NDA government was afraid of constituting a joint parliamentary committee (JPC) if no wrongdoings was done in the purchase.“Even Sita Maiya (Goddess Sita) had to go through an ‘agni-pariksha." Why PM Narendra Modi is not ready to face a probe into the Rafale purchase by a JPC in which the BJP obviously would have larger number of MPs?” Congress national spokesperson and its Bihar in-charge Shaktisinh Gohil asked while addressing a press conference here.Reiterating the Congress’ demand for constitution of a JPC, Gohil said, “Once a JPC is constituted it will go through every aspects of the purchase process and everything will be known to people of this country.”Terming the controversial Rafale deal as the ‘grandmother of all corruption’, Gohil said his party would organise demonstration and protest rallies at district level across the country including Bihar from September 6 to 15 to inform people as to how Modi government was going to purchase Rafale fighter aircrafts at three-time higher rate than the rate fixed by the previous UPA government.Flanked by the State Congress incharge president Kaukab Qadri, MLC Prem Chandra Mishra and newly appointed AICC secretary for Bihar and Gujarat MLA Alpesh Thakore, Gohil said the previous UPA government had made an agreement with a France-based company to purchase 126 Rafale fighter aircraft at the rate of Rs 526.10 crore.“But in October 2015, PM Modi visited France and made a joint announcement there to purchase only 36 Rafale aircrafts in place of 126. Later the Dassault company, which manufactures Rafale fighter aircraft, tabled a report in France Parliament in which it revealed the price of each aircraft at Rs 1670.70 crore at which the deal was reportedly finalised with India,” Gohil claimed and wondered how the rate shot up three times.To a question, Gohil said the Congress might consider filing a petition before an appropriate court seeking probe into the Rafale purchase, if the Modi government didn’t constitute JPC or allow an inquiry by the Comptroller and Auditor General of India.Despite requests from media persons, Gohil declined to take questions on any other issues be it the issue of seat-sharing among the partners of grand alliance or Bihar’s law and order scenario, saying “This press conference was specially called to discuss the matter of Rafale purchase.” He said Congress had asked all its senior leaders to go to different cities and hold such press conferences on Rafale issue. Similar press conferences would be organised in 90 cities across the country, Gohil said.
