In a medical bulletin issued on Saturday, the private hospital said, "In view of the criticality of Parkash Singh Badal's health, he continues to be closely monitored in the medical ICU."
Defence Minister Rajnath Singh and Home Minister Amit Shah have enquired about his health and prayed for his speedy recovery.
In June last year, Badal, who had been the chief minister of Punjab for five terms, was hospitalised following complaints related to gastritis and bronchial asthma.
In February 2022, he was taken to a private hospital in Mohali for a post-Covid health check-up during which he had undergone cardiac and pulmonary check-ups too.
In January 2022, he was admitted to a hospital in Ludhiana after testing positive for COVID-19.
