Health condition of Group Captain Varun Singh is still critical but he is stabe. GC Varun Singh is the only survivor in the December 8 chopper crash in which CDS Bipin Rawat, his wife and 11 armed forces others lost lives.

GC Varun Singh’s father, Colonel KP Singh (retired), who lives in Bhopal, said his son's health condition is fluctuating but believed that he would win the battle as he is a "fighter".

Group Captain Singh, a decorated officer, was on board the Russian-made chopper as the liaison officer for the visit of General Rawat to the Defence Services Staff College in Wellington.

Talking to PTI over the phone from Bengaluru, Colonel KP Singh (retired), who retired some ten years ago, said, "There is so much of fluctuation that how (my son is) cannot be defined." He added that his son's health is being monitored every hour.

"In the hourly monitoring, there are rises and falls. You cannot say. Everyone is discussing. We are in the best hands. He is in the best hands, rather," the retired Army officer added.
