Former President Pranab Mukherjee's health has shown "positive signs of improvement", his son Abhijit said today. The 84-year-old was admitted to the hospital last Monday and was operated upon for removal of a clot in the brain. He is also COVID-19 positive.

Over after a week, it is for the first time that Mukherjee's health condition has improved. "My father is stable now. His vital parameters continue to remain under control and manageable. Positive signs of his improvement noticed," Abhijit Mukherjee said in a tweet this morning.
