ONGC hasn't had a chairman in office for over 24 hours

As the hierarchy stands, the senior-most director in the organisation - Alka Mittal, director (HR) - would take over from Kumar. However, that is subject to a government order. As it stands, the last administrational order from the Oil Ministry - issued on December 28 - gave Anurag Sharma, the onshore director, the additional responsibility of finance director.
