"In the interim, C S Rajan, MD, IL&FS, has been asked by the board to discharge Nayyar’s responsibilities and, in consultation with senior management, put in place a revised organisational structure," IL&FS said in a statement.

He oversaw the resolution of IL&FS and its 300 companies, for the last two years. Nayyar had also overseen the resolution of Satyam after a scam by the founder Ramalinga Raju.
