The Army Chief Gen. V. K .Singh today interacted with Parliament's Public Accounts Committee (PAC) in connection with alleged irregularities in the canteen stores supplies. Official sources said, senior Army officials made a presentation of management of rations in the Army. General Singh briefed the PAC headed by senior BJP leader Murli Manohar Joshi at around 11 AM. Air Chief P V Naik is likely to appear before the Committee later in the day. Talking to reporters in New Delhi on Tuesday, Air Chief Marshal Naik had said that the armed forces have decided to stick to their stand that their unit-run canteens (URC) are beyond the purview of the PAC.The Navy would be represented by Vice Chief D K Deewan, as Navy Chief Nirmal Verma is in Indonesia on a pre-scheduled four-day visit which began on Sunday.The PAC had written to the Defence ministry asking for a consultation with the chiefs of the three defence services after a CAG report pointed out irregularities in the supply chain management of rations by Canteen Stores Department (CSD). The ministry of defence had advised the service chiefs to appear before the PAC apparently to underline the committee's immense significance. Usually, the Defence Secretary attends meetings of the Parliamentary Committees along with Vice Chiefs of the Services.
