New Delhi: In the wake of allegations that the Intelligence Bureau was trying to tarnish his image, Chattisgarh Chief Minister Ajit Jogi would soon be questioned by the Central Bureau of Investigation (CBI) to clear the air.

The CBI has already written to the Chief Minister asking for "some time" so that some questions could be asked to him about the allegations levelled by him that the IB unit in Raipur was trying to target him deliberately under a plan code-named "Operation Black Sea", highly-placed sources said.

The sources said his co-operation was necessary to reach to the bottom of the case.

The sources said the CBI was investigating to determine the authenticity of documents furnished by Jogi in connection with his allegation that the IB had launched an "operation" to defame Bharatiya Janata Party (BJP)'s political opponents.

Jogi had alleged that the operation, had been launched by the IB special directorate to target Opposition leaders, including Congressmen like him, in the run-up to the election campaign in Congress- ruled states.

Jogi had said "someone gave a photocopy" of the "operation" launched against him in which it was alleged that he had a joint account in a Swiss bank along with his wife and had amassed money and property since he became the Chief Minister.

The sources said some more aspects of the case were being discussed and questioning of some more people would be undertaken by the agency.
