The sale of five state-owned sugar mills in Uttar Pradesh to Ponty Chaddha, a businessman close to the state's Chief Minister Mayawati, is being investigated for corruption. The mills were sold to Chaddha's company for Rs. 206 crore, far below their estimated market value of over Rs. 2,000 crore. Opposition parties are demanding a CBI probe into the low-price sales. An investigation by the state Lokayukta is already underway following complaints about the undervalued sales. The CAG is also auditing the transactions and has found irregularities in how the assets were valued and bidding process conducted.
