“All his parameters are fine. He is under observation at the AIIMS,” a source close to him said, adding that he was taken to the hospital after he felt “uneasiness”.
Singh is a senior leader of the opposition Congress and currently represents Rajasthan in the Upper House of Parliament. He was the prime minister between 2004 and 2014.
Rajasthan chief minister Ashok Gehlot expressed concern over the health of Singh. “Much worried to know former PM Dr. Manmohan Singh Ji has been admitted to AIIMS. I wish him a speedy recovery and pray for his good health and long life,” Gehlot tweeted.
The former PM has had health concerns earlier too. He underwent heart-bypass surgery at AIIMS in 2009, in which five grafts – channels to bypass blocked arteries – were implanted in surgery that too over 10 hours.
In May 2008, he had undergone a cataract operation, and in September 2007, he had prostate surgery. He also underwent a bypass in the United Kingdom in 1991.
