Congress leader Sharmistha Mukherjee on Wednesday posted an emotional message for her father Pranab Mukherjee on twitter after the former president went through a brain surgery.

"Last year, August 8 was one of the happiest day for me as my dad received the Bharat Ratna. Exactly a year later, on August 10 he fell ill. May god do whatever is best for him and give me strength to accept both joys and sorrows of life equanimity. I sincerely thank all for their concerns," she tweeted.

Pranab Mukherjee remains critical after undergoing a brain surgery for the removal of a clot. He had earlier tested positive for Covid-19.  He is currently on ventilator support at the Army's Research and Referral Hospital in Delhi.
