Copies of certain contracts entered by AgustaWestland with various entities in Tunisia and India have also been provided by the Italian government.

In reply to a separate question on court martial of a Commanding Officer and other personnel of an artillery unit, he said, "Based on an Army CoI, disciplinary action has been initiated against four officers including the CO, 17 Junior Commissioned Officers (JCO) and 147 Other Ranks."
He was asked whether the Army CoI has recommended Court Martial proceedings against 168 personnel including the Commanding Officer of the artillery unit.

Replying to a question whether services of some DRDO scientists, allegedly involved in terror plot, were terminated, he said, "No scientist of the DRDO has been allegedly involved in terror plot." However, he said, "Services of Aijaz Ahmed Mirza, who was holding the post of Junior Research Fellow (JRF) in the Centre for Air Borne Systems (CABS) at Bengaluru, got terminated on February 12, 2013 due to prolonged absence from duty from August 30, 2012 and also arrest by police for his alleged involvement in terror plot."
Mirza was appointed as JRF on short term basis for a period of two years with effect from January 9, 2012. "He was not a regular scientist of DRDO and not assigned any sensitive classified job," Antony said.
Mirza was granted bail by a Special Court under the National Investigation Agency (NIA) at Bengaluru on March 5. "Further investigation is being continued by the investigating agency. Reinstatement of Mirza can be considered after getting confirmation of his innocence from Investigation Agency/Court," he said.
