SINGAPORE - Good wishes have poured in for former president S R Nathan, after news broke of his hospitalisation following a stroke last Tuesday.

Prime Minister Lee Hsien Loong joined the well-wishers on Thursday, saying in a Facebook post that he was saddened to learn last week that Mr Nathan had suffered a stroke.

He and his wife Ho Ching visited Mr Nathan at the Singapore General Hospital last Friday.

"We were glad to see him sitting up, and in good spirits. He has always been a fighter," wrote Mr Lee. "Hope he continues to recover well."

The post gained over 13,000 likes and more than 400 comments, with netizens wishing Mr Nathan well.

Others also took to social media to express their concern for Mr Nathan and to wish him a speedy recovery.

On Wednesday, President Tony Tan said on Facebook that he and his wife had earlier this week visited Mr Nathan, who was "in good spirits and looking forward to being discharged".

Emeritus Senior Minister Goh Chok Tong, too, visited Mr Nathan in the hospital, and found him alert and clear-headed, he said on Facebook.

Mr Nathan is also able to speak normally and move his hands freely.

"He is making good recovery from his stroke and should be discharged soon," said Mr Goh.

The People's Action Party has started a #getwellsoonSRNathan hashtag on its social media accounts.
