Doctors at Gurgaon's Medicity Medanta Hospital on Monday said the condition of former prime minister Inder Kumar Gujral is "very critical".
Gujral, 93, was admitted to the hospital in Gurgaon with a lung infection on November 19, and doctors said he is still on ventilator support.
"He is very critical, medicines are not showing much effect, good wishes can help him better," a senior medical consultant, who did not wish to be named, told reporters.
Another senior consultant at the hospital termed Gujral's condition "critical but stable".
"The condition of the former prime minister is critical but stable and changing minute by minute," admitted the consultant, also speaking on condition of anonymity.
A team of nine senior consultants headed by Dr Naresh Trehan is keeping a close watch on Gujral.
