Teh Cheang Wan

On 26 Jan 1987, Lee Kuan Yew delivered a parliamentary speech by reading out the suicide note addressed to him, written by Teh. He then revealed for the first time that Teh was being investigated for accepting bribes. Lee stressed that "there is no way a Minister can avoid investigations, and a trial if there is evidence to support one." Later in the book titled "Lee Kuan Yew: The Man and His Ideas", published in 1998, Lee reiterated the importance of having a system where people act in accordance with certain principles.

However, there was a subsequent investigation into the matter as a result of allegation of Chiam See Tong, the opposition MP, that there were unanswered questions into the whole episode. On 20 January 1987, the State Coroner returned a verdict of suicide due to an overdose of amytal barbiturate. In December 1987, the findings of the Commission of Inquiry were presented to the President of Singapore, however, they were not released to the public till the end the year. The entire probe lasted 31 months.

In November 1986, the former Prime Minister of Singapore, Lee Kuan Yew, approved an open investigation on his alleged corruption; however, the papers were issued to the Attorney-General on December 11. Though Teh maintained his innocence, he committed suicide before being charged for the offences, on December 14.

As Minister for National Development, Teh proposed a ban on chewing gum in 1983 in light of public cleanliness issues. Then-Prime Minister Lee Kuan Yew rejected the idea as being too drastic, but 9 years after Teh's initial proposal, a chewing gum ban was passed into law.
