The Congress on Saturday demanded that an FIR be lodged by the CBI against persons in the Aam Aadmi Party government responsible for siphoning off public funds for private purposes.Addressing a press conference here, Congress Delhi Chief Ajay Maken said that the amount being used for advertising under the AAP government's tenure in Delhi has increased 14.5 times as compared to previous governments.The Congress also accused the Arvind Kejriwal government of misusing public funds for "political activities of the Aam Aadmi Party".Maken told reporters here: "During 2014, when Delhi was under President's Rule, the total amount spent on advertising was Rs 14.5 crore. The very next year, the Arvind Kejriwal-led government, spent Rs 127 crore on advertisements and in the current fiscal it's Rs 207.73 crore." The Congress leader accused the Delhi Government of ignoring the Supreme Court guidelines on advertising, and said the Comptroller and Auditor General of India (CAG) supports his allegations.
