SMU Chairman and the founder-chairman of Banyan Tree Holdings Mr Ho Kwon Ping in a candid dialogue session opened up on his detention under the Internal Security Act (ISA) four decades ago, in front of a record audience of 350 at the sixth edition of The Straits Times Book Club on 29 August 2018. Mr Ho was discussing his new book, Asking Why, a collection of his speeches and writings, with The Straits Times' Associate Editor Ravi Velloor at the National Library headquarters’ programme zone. On his detention under ISA, he described the decision to detain him as “wrong” but understood why it was taken. During the session, Mr Ho also warned against a lack of diversity in the next generation of Singapore’s political leadership.
