AIIMS chief Dr Randeep Guleria, who heads the sub group that led the audit on Delhi oxygen, said that the final report is not out yet. Dr Guleria also said that it would not be correct to say that Delhi "exaggerated" its oxygen needs by four times during the second wave of Covid. "I can't say for sure about the four times exaggeration of oxygen demand." The observations of the report has set off a new clash between the Centre and Arvind Kejriwal's Aam Aadmi Party (AAP) government in the capital.
