Senior Congress leader Ahmed Patel, who tested positive for coronavirus on October 1, has been admitted to the ICU of Gurgaon's Medanta Hospital, his family said on Sunday.
A tweet posted by his son, Faisal Patel, said the veteran politician's condition is "stable" and that he "continues to be under medical observation".
"On behalf of his family, we would like to share that Shri Ahmed Patel had tested positive for Covid19 a few weeks ago. He has now been admitted to the Intensive Care Unit of Medanta Hospital, Gurgaon for further treatment.

"Deeply concerned and praying for the good health of my friend and comrade Ahmed Patel. Please join us in praying for his early recovery," senior Congress leader Anand Sharma tweeted.
