Former president S R Nathan was discharged from the Singapore General Hospital on Saturday, almost three weeks after he suffered a stroke.
A source close to the 90-year-old told The Straits Times on Sunday: "He is back to normal and simply needs more rest. He will do so at home."
During his time in hospital, Mr Nathan was visited by President Tony Tan Keng Yam, Prime Minister Lee Hsien Loong and Emeritus Senior Minister Goh Chok Tong, among others.
Mr Nathan is Singapore's longest-serving president, having served two six-year terms as head of state from 1999 to 2011. He has also been a social worker, trade union activist and diplomat.
