The Central Bureau of Investigation on Thursday told the Supreme Court that there was 'sufficient' evidence to prosecute Uttar Pradesh Chief Minister Mayawati in a disproportionate assets case, registered against her five years ago.

The investigating agency filed an affidavit in the apex court saying it will shortly file a chargesheet in the disproportionate assets case registered against the Bahujan Samaj Party supremo in 2003.

It said there was ample evidence to show that she amassed wealth disproportionate to her known source of income.

CBI was responding to the notice issued to it on the petition filed by Mayawati seeking quashing of the criminal proceedings against her in the case alleging that it was foisted on her due to political reasons.

The affidavit said that investigations into the case has been concluded and there are sufficient evidence to chargesheet her.
