Health Minister Ong Ye Kung said he was saddened by Dr Koh’s decision to step down.
“I know that the matter has been weighing on his mind. I am glad that he has come to a decision, and respect him for doing what he feels is best for his family,” Mr Ong said in a Facebook post on Friday.
Mr Ong added that he would miss Dr Koh as a “close colleague”, as well as his “honest counsel” at the Ministry of Health (MOH).
“Being a doctor, a hardworking MP, and a grounded person, he will always have a useful perspective on healthcare issues,” he said.
Mr Ong also said he was happy that Dr Koh would continue to serve as a Member of Parliament and adviser to his constituency, and wished him and his family all the best.
