DW BUREAU / chandigarh The Shiromani Akali Dal (SAD) today expressed surprise why the central government had not taken note of the "Call Gate" scandal involving Republic Television Editor Arnab Goswami saying the BJP government should not let any media house compromise national security at any cost. In a statement here, former minister Maheshinder Singh Grewal said it was shocking that despite disclosures revealing that Arnab Goswami had even leaked information about the Balakot strikes, the NDA government was yet to order an inquiry into the case. "Keeping in view the fact the central government has done nothing in the case we demand the Chief Justice of the Supreme Court probe the case as the nation wants the truth in the case to be presented before the people." Grewal said the Chief Justice could even constitute a double bench to hear the entire case in a time bound manner. Maheshinder Grewal also requested Prime Minister Narendra Modi to launch a separate investigation against officials of the Prime Minister's Office (PMO) who leaked sensitive information to Goswami on a regular basis as revealed in conversations between the latter and the Broadcast Audience Research Council chief Partho Dasgupta. "It is clear from the conversations which are now in public domain that Goswami had access to top constitutional, ministerial and administrative appointments. It should be ascertained as to who leaked this information and whether any cabinet minister was also involved in the conspiracy to pass on information concerning the surgical attack to an enemy nation." He also said that it is also a fact that there was barely any top minister of his cabinet who did not jump to his defence in indignation when he was arrested as compared to today when #arnabChatgate is exposed. He said that not only there is deadly silence from GOI but all channels have also been muzzled from carrying the news. The SAD leader also demanded a separate investigation into classified information in the possession of the Republic TV Editor as well as other staff members who were purview to the same. "Mr Goswami should submit himself to questioning in this regard in the nation's interest. After all the unity and integrity of our nation is above everything," Grewal added. Meanwhile, PTI has reported that the News Broadcasters Association (NBA) on Monday said ratings of television news channels should remain suspended till the TV ratings agency takes action to address concerns and shares details of it with the stakeholders. In a statement, Rajat Sharma-headed NBA said it is "shocked to see hundreds of WhatsApp messages that have been exchanged between BARC India's former CEO -- Partho Dasgupta -- and Arnab Goswami, Managing Director, ARG Outlier Media Pvt. Ltd". It demanded that the Indian Broadcasting Foundation (IBF) membership of Republic TV should be suspended with immediate effect till the case related to manipulation of ratings is pending in court.According to the statement, the NBA urged the BARC to come up with a clear statement about the veracity of its ratings in the period during the audit and also conduct an audit of the Hindi news segment. "Expunge the data of the erring broadcaster and restate the real position of rankings of all news channels from the beginning," it demanded from the ratings agency. (editor@dailyworld.in)
