that year under the slogan of "Singaporeans for Singapore", raising the need for elected opposition in parliament to bring democracy to Singapore. The party also raised other prominent issues of the time such as the need to reform the education and CPF system, and its opposition to the Elected Presidency. It noticeably fielded only four candidates in that general election: Secretary-General Chiam See Tong, Chairman Ling How Doong (who was elected Chairman after the death of Fok Tai Loy), Vice-Chairman Soon Kia Seng and treasurer Peter Lim Ah Yong. During the campaigning, the party came under fire from the ruling's People's Action Party (PAP), with Ling and Chiam bearing the brunt of the attacks. The PAP chose to highlight Ling's dismissal from the police force and the record of his election agent, but these were quickly rebutted by the SDP leadership. Chiam saw his secondary school record being brought up by the then-Prime Minister Lee Kuan Yew, who compared Chiam's intelligence with that of PAP's Mah Bow Tan (a candidate who later became a cabinet minister and then-MP of Tampines GRC) who was standing against the SDP leader. Chiam won the single seat of Potong Pasir after three attempts in the constituency by a vote of 60.3% to Mah's 39.7%, making Chiam as only the second opposition politician ever to be elected to the Republic's Parliament after J.B. Jeyaretnam of the Workers' Party. The SDP garnered 45.2% of total votes cast in the constituencies they had contested in. After Jeyaretnam was expelled from Parliament in 1986, Chiam was Singapore's sole opposition MP. A moderate, Chiam claimed that he was not opposing for the sake of opposition. He also said: "But if they (the government) do the wrong things which are not good for Singapore, then we will oppose fearlessly". 1988 general elections The 1988 general elections saw the opposition's strongest challenge since 1963, with 71 out of 82 seats contested. This election also saw the PAP engage the SDP's Chiam and WP's Jeyaretnam in a television debate. Besides Chiam and Ling, the SDP also fielded Ashleigh Seow (the son of former Solicitor-General Francis Seow), businessmen Jufrie Mahmood, Cheo Chai Chen and Ng Teck Siong, sales manager Kwan Yue Keng, bank clerical assistant Mohd Shariff Yahya, teacher George Sita, financial futures trader Jimmy Tan, former PAP MP Low Yong Nguan, businesswoman Toh Kim Kiat, construction supervisor Francis Yong Chu Leong, shipping
