Ling How Doong (; 1935/1936 – 30 April 2021) was a Singaporean politician and lawyer who served as chairman of the Singapore Democratic Party between 1984 and 2007 and the Member of Parliament (MP) for Bukit Gombak SMC between 1991 and 1996. Education Ling was educated at Anglo-Chinese School and Nan Hua High School. He was called to the Bar at the Middle Temple in London in 1972 to practice as a lawyer. Political career Ling was the chairman of the Singapore Democratic Party in 1991 when, in a surprise result, he defeated the incumbent MP from the governing People's Action Party (PAP), Dr. Seet Ai Mee, to win the constituency of Bukit Gombak at the general election. Ling won 51.4% of the votes in the constituency to Dr Seet's 48.6%. Ling was one of three SDP MPs to be elected – with the party's leader Chiam See Tong retaining his seat in Potong Pasir, and Cheo Chai Chen winning in Nee Soon Central. The leader of the Workers' Party, Low Thia Khiang, was also elected in Hougang, giving the opposition parties a total of four seats. At the previous election, Chiam had been the only opposition MP to win a seat, so the results were seen as a significant success for the opposition. In 1994, the SDP appointed Ling to take over from Chiam as the party's parliamentary leader after Chiam fell out with the rest of the party's Central Executive Committee (CEC). Chiam resigned as the party's Secretary-General and was replaced by Chee Soon Juan. Ling hit the headlines in 1995 after Chiam whispered something into his ear during a debate in Parliament, to which Ling loudly responded "Don't talk cock!" (a Singlish phrase meaning "Don't speak nonsense"). Ling was formally censured by Parliament for using inappropriate language in the chamber as a result of this. Ling was defeated in his bid to be re-elected as MP for Bukit Gombak at the 1997 general election, losing to the PAP's Ang Mong Seng. Ling won 28.4% of the votes to Ang's 65.1%, with Syed Farid Wajidi from SPP taking 6.5% of the votes. For the 2001 general election, Ling's old seat of Bukit Gombak was abolished following boundary changes. Ling stood in Cheo's former constituency of Nee Soon Central, and was defeated by the PAP's Ong Ah Heng. Ling received 21.5% of the votes to Ong's 78.5%. At the
