R.K.Singh's outburst due to no post-retirement job: Narayanasamy

Defending Shinde, Narayanasamy said he has "impeccable integrity". "He is a man of action. He has made several reforms, and law and order situation has improved across country," he said.

External Affairs Minister Salman Khurshid meanwhile said R.K. Singh should have made these comments when he was in office.

"The point is if Mr. Shinde had a point of view, and he (R.K. Singh) disagreed, he should have made that disagreement known. Nobody can stop a legitimate investigation taking place. So Mr. R.K. Singh must realise he is actually condemning himself every time he speaks," Khurshid told the Times Now T.V. channel.
