Former President Pranab Mukherjee's health condition remains critical on Thursday, following his emergency brain surgery three days back. He continues to remain on ventilator support at the Army Research and Referral Hospital.

The hospital authorities said: "The condition of Pranab Mukherjee remains unchanged this morning. He is deeply comatose with stable vital parameters and continues to be on ventilator support."

Mukherjee, the 13th president of India, was also found to be Covid-19 positive.

The hospital authorities issued a statement after fake news started appearing on social media platforms about Mukherjee's health condition.

The former President's son Abhijit Mukherjee refuted speculations around Mukherjee's worsening health saying his father is 'alive'. "My Father Shri Pranab Mukherjee is still alive and haemodynamically stable! Speculations and fake news being circulated by reputed Journalists on social media clearly reflects that Media in India has become a factory of Fake News," tweeted Abhijit Mukherjee.

Mukherjee's daughter Sharmistha Mukherjee, who is also a Congress functionary, too refuted the rumours about her father.
