On Friday, Mr. Chawla resigned as Chairman of the National Stock Exchange after the CBI got the nod to prosecute him in the Aircel-Maxis bribery scandal.

Former finance secretary, Ashok Chawla, has resigned as Chairman of The Energy Resources Institute (Teri).

Teri Director General, Ajay Mathur, told The Hindu that Mr. Chawla had resigned on Friday night. "Yes he's resigned. We are now internally consulting with other council members on the steps ahead, " he said in a phone conversation.

Mr. Chawla had replaced B.V. Sreekantan Nair as the Chairman in February 2016. Mr. Nair resigned following a change in the council's leadership in the aftermath of the resignation of R.K. Pachauri, who was asked to stepdown after charges of sexual harrassment.

On Friday, Mr. Chawla resigned as Chairman of the National Stock Exchange after the CBI got the Finance Ministry's approval to prosecute him in the Aircel-Maxis bribery scandal.

After the CBI filed a chargesheet last June, some employees had demanded his ouster but the organisation had refrained from taking action on the grounds that a chargesheet wasn't reason enough for his ouster.

Mr. Chawla was also a former head of the Competition Commission of India.
