The two "tainted" ministers put in their papers following a directive to the effect by the Congress high command, sources said.
Sabita and Prasada Rao met the Chief Minister at his camp office late tonight and submitted their resignations and left the place in their private vehicles, the sources said, but there was no confirmation from the CMO on the resignations.
Prasada Rao had submitted his resignation earlier and even stayed away from duties for long, but he was asked to continue in office.
Sabita too had offered to quit, but she was also persuaded not to resign.
While Prasada Rao, the then Revenue Minister in the Y S Rajasekhara Reddy government, was named as an accused in CBI chargesheet in the Vanpic land allotment scandal, Sabita, who was previously Minister for Mines, was listed as an accused in the illegal allocation of mines to certain cement companies.
