By Toh Han Shih In the second volume of his biography, former Singapore Prime Minister Goh Chok Tong revealed his soft spot for two former stalwarts of the ruling Peopleâs Action Party (PAP), the late Ong Teng Cheong and Dr Tan Cheng Bock, even though these two men opposed the PAP after leaving the party. In the book, Standing Tall, Mr Goh expressed warmth and admiration for these two men whom he called friends, in contrast to his dislike for opposition politicians Chee Soon Juan and Tang Liang Hong. The book, which details Mr Gohâs tenure as Prime Minister from 1990 to 2004, hit the bookstores earlier in May. It is a sequel to the first volume, Tall Order, which covered Mr Gohâs youth, working life and earlier political career.
