SINGAPORE - Former president S R Nathan is warded in the Singapore General Hospital after he suffered a stroke last Tuesday.
"He is recovering and is now undergoing therapy," said Mr Nathan's family in a statement on Wednesday.
A source close to the 90-year-old told The Straits Times on Wednesday: "He's doing well. But just like before, his ability to walk is not so strong. The therapists are trying to make him stronger."
Mr Nathan, who previously was frequently seen taking walks along East Coast Park, said in an interview with The Straits Times in January that he had not been able to do so for more than six months.
He had said at the time: "I cannot walk any distance. My health is not good. I became breathless and tired. But my mind is okay."
Mr Nathan has served Singapore as social worker, trade union activist, diplomat, and elected President.
He was Singapore's longest-serving President, serving two six-year terms as head of state from 1999 to 2011.
In 2013, he became only the seventh person in Singapore's history to be conferred the top National Day honour - the Order of Temasek (First Class).
President Tony Tan Keng Yam, who visited Mr Nathan in hospital earlier this week, commented on Mr Nathan's condition in a Facebook post on Wednesday.
