The Comptroller and Auditor General (CAG) has unearthed a Rs 1,200-crore scam in the sale of 21 sugar mills, during Uttar Pradesh Chief Minister Mayawati’s regime, on account of discrepancies in the valuation of land and machinery. Transactional advisor, IFCI, has also come under attack from the auditor for lowering valuations. A number of these mills went to liquor distributor Ponty Chadha, perceived to be close to Bahujan Samaj Party (BSP) supremo Mayawati.
