Pradip Chandra had taken over as Chief Secretary on December 1. Though it was expected that he would get an extension for another three months, the state government did not receive any such communication from the Centre till Saturday and hence the Chief Minister has decided to appoint Singh as the new CS. It may be mentioned here the first Chief Secretary of the state, Rajiv Sharma, who retired as Chief Secretary on November 30, was given two extensions, three months each, since May 31. Though there were other senior IAS officers like M G Gopal and S K Joshi in the race, sources said, the Chief Minister has chosen Singh as the successor to Pradeep Chandra.
