Former prime minister and Congress leader Manmohan Singh on Tuesday visited former prime minister Atal Bihari Vajpayee at Delhi's All India Institutes of Medical Sciences (AIIMS).
Vajpayee, who was admitted to the hospital on Monday, is undergoing treatment for urinary tract infection. His condition is said to be stable.
Earlier, Prime Minister Narendra Modi and many senior Bharatiya Janata Party (BJP) leaders L.K. Advani, Rajnath Singh, Amit Shah and Congress president Rahul Gandhi visited Vajpayee.
AIIMS official, Dr. (Professor) Aarti Vij earlier, in a statement, said, "Former Prime Minister Vajpayee's condition is stable. He is responding to treatment and is on injectable antibiotics. All vital parameters are stable. He will continue to be in hospital till the infection is controlled."
Vajpayee, who led the National Democratic Alliance government from 1998-2004, was the first ever person from the BJP to have become the nation's prime minister.
He served as prime minister thrice - briefly in 1996, and for two terms between 1998 and 2004.
