New Delhi, July 9 (IANS): Home Minister Rajnath Singh called on President Pranab Mukherjee on Thursday amid speculation on the continuation of Madhya Pradesh Governor Ram Naresh Yadav.

Yadav was issued notice by the Supreme Court during the day on a plea with regards to the forest guard recruitment scam.

Officials said the two leaders had a one-to-one meeting but gave no details. They said the meeting was pre-scheduled.

Earlier in the day, Home Secretary L.C. Goyal met Rajnath Singh after the apex court notice to the Madhya Pradesh governor.

The Supreme Court had issued notice to the central government, the Madhya Pradesh government and Yadav on a plea challenging the state high court order quashing an FIR against Yadav over his alleged involvement in the recruitment scam on the ground that he enjoyed immunity of the constitutional office he was occupying.

Yadav's son Shailesh Yadav, an accused in the Madhya Pradesh Professional Examination Board (or Vyapam) scam, was found dead under mysterious circumstances in March at his father's residence in Lucknow.

Bharatiya Janata Party leaders indicated on Thursday that the party would not defend Ram Naresh Yadav and he may have to resign.

"People occupying constitutional posts should introspect whether their actions are adding to the esteem of their office or not," BJP spokesperson Nalin Kohli told IANS.

He said Yadav was appointed governor by the Congress-led United Progressive Alliance government and he was considered close to the Congress leadership.
