CBI cracks how Mayawati grew rich in 3 years Bhupendra Chaubey CNN-IBN New Delhi: The Central Bureau of Investigation (CBI) is all set to file a charge-sheet against UP Chief Minister Mayawati for allegedly owning wealth disproportionate to her known sources of income. CNN-IBN learns that the CBI, in a 12-page charge-sheet, has alleged that Mayawati failed to explain how her wealth increased from Rs 1.35 crore to Rs 52 crore in three years. Mayawati, chief of the Bahujan Samaj Party, declared her she owned Rs 1.5 lakh in cash, Rs 9.78 lakh in bank deposits and properties worth Rs 1.25 crore in Delhi when she filed an election affidavit on April 4, 2004 from the Akbarpur Lok Sabha constituency. Her fortunes changed dramatically in three years, alleges the investigative agency. Mayawati, in the 2007 Assembly elections, filed an affidavit declaring her assets at Rs 52 crore. The CBI refutes Mayawati's defence that she got money from party workers as donations. It claims it has statements of some BSP workers, who deny giving money to Mayawati though she has named them as donors. The CBI charge-sheet is likely to make relations between the Congress-led United Progressive Alliance (UPA) government and the BSP worse. Mayawati alleges the FIR against her in the Rs 175-crore Taj Heritage Corridor scam is political harassment. The FIR was filed on October 5, 2003 and forms the basis of CBI’s charge-sheet. The BSP also alleges that the CBI pressured BSP MP Brijesh Pathak to vote for the UPA government during the confidence motion in Parliament in July 2008, but the agency rejects the accusation and claims it is tactic to delay its probe. The charge-sheet is to be filed before the Supreme Court on Monday and the UP government will then seek two weeks to file its reply.
