Cheng San Group Representation Constituency

History

1988: Establishment

Cheng San GRC was established in 1988, following the establishment of GRC and Single Member Constituency (SMC), by merging the Cheng San, Chong Boon and Jalan Kayu Constituencies. The GRC was originally represented by three MPs. During the 1991 general election, it absorbed Punggol SMC and was expanded to a four-member GRC. In that election, the PAP secured 64.05 percent of the valid votes, while the National Solidarity Party (NSP) team received 35.95 percent.

1997: Hotly contested election

During the 1997 general election, Cheng San GRC underwent boundary changes. Parts of the Chong Boon division, bounded by Ang Mo Kio Avenue 10, Ang Mo Kio Avenue 3, the Central Expressway and Ang Mo Kio Avenue 1, were absorbed into Ang Mo Kio GRC. At the same time, the Punggol division was split into three divisions: Punggol Central, Punggol East and Punggol South, reflecting the population growth in Hougang and Sengkang. As a result of these adjustments, Cheng San became a five-member GRC.

The constituency was hotly contested between the People's Action Party (PAP) and the Workers' Party (WP) in 1997. The PAP team was led by Lee Yock Suan, then Minister for Education, while the WP team was headed by its Secretary-General Joshua Benjamin Jeyaretnam alongside senior lawyer Tang Liang Hong. The PAP campaign received heavy support from Prime Minister Goh Chok Tong, PAP's Secretary-General, and his two deputies, who all campaigned actively in Cheng San. Goh described himself as "a special candidate" of the constituency, declaring that his credibility and reputation as Prime Minister were "at stake" in the contest.

The PAP campaign adopted a two-pronged approach. First, the party accused Tang of being "anti-Christian" and a "Chinese chauvinist", branding him a "dangerous man". Second, Goh promised voters that returning PAP candidates would secure improvements such as new transport links through the Mass Rapid Transit (MRT) and Light Rail Transit (LRT), housing projects like Punggol 21 and opportunities to upgrade HDB estates. The PAP stressed that constituencies which did not elect PAP candidates would not be prioritised for upgrading and risked "deteriorating into slums". Meanwhile, the WP drew large crowds at its rallies in Cheng San, with an estimated 50,000 people attending its final rally at Yio Chu Kang Stadium on the eve of polling. However, reports of the turnout were downplayed in The Straits Times, leading to criticism of the newspaper's neutrality.

Presence of PAP politicians at polling stations

On Polling Day, several senior PAP leaders, including Goh Chok Tong, Tony Tan and Lee Hsien Loong, were present within the precincts of polling stations in Cheng San GRC, despite not being candidates in the constituency. The WP argued that their presence contravened the Parliamentary Elections Act, which prohibits unauthorised persons from entering polling stations in order to prevent undue influence or intimidation of voters and staff. The WP candidates subsequently lodged police reports, citing alleged breaches of two sections of the Parliamentary Elections Act:

• Section 82(1)(d): "No person shall wait outside any polling station on polling day, except for the purpose of gaining entry to the polling station to cast his vote".
• Section 82(1)(e): "No person shall loiter in any street or public place within a radius of 200 metres of any polling station on polling day."

Their complaints were however not prosecuted by the police, on the advice of the Attorney-General (AG) Chan Sek Keong. Chan, in his letter to the Minister for Law S. Jayakumar, argued that the statute was "irrelevant" to individuals inside a polling station. This interpretation was unusual, as it meant that remaining inside the station was permissible, while being in the surrounding area within 200 metres of its external walls was considered an offence. He further stated that "the possibility of a person inside a polling station influencing or intimidating voters in the presence of the presiding officer, polling officials and polling agents was regarded as so remote that it was discounted by the Act." This reasoning was also peculiar, as it implied that being inside the polling station posed no risk of undue influence, whereas merely standing within 200 metres outside could.

The WP rebuked this interpretation, questioning whether the AG was suggesting that it was acceptable for people to enter and remain on the grounds of the polling station, while it was not permissible to stand outside the station. The WP subsequently renewed its call for a neutral and multi-party election commission to safeguard fair play in the conduct of general elections.

Results

The counting of the ballots was delayed; a WP candidate and two counting agents had lodged objections after the first batch of ballot papers were counted. The PAP ultimately retained Cheng San GRC, receiving 54.82% of the vote. As the WP team in Cheng San GRC were the "best losers" in an election with fewer than six elected opposition MPs, they were offered one seat for a non-constituency Member of Parliament (NCMP). Jeyaretnam was selected by the WP to accept the seat, which he did.

Following the election, Tang was sued for defamation by various PAP ministers and subsequently fled to Australia. Jeyaretnam lost his NCMP seat after being declared bankrupt in July 2001, as undischarged bankrupts are barred from serving in Parliament and standing in parliamentary elections. He died in 2008, while Tang, who died in 2025, never returned to Singapore after the election.

2001: Abolition

After a hotly contested election in 1997, the GRC was split and subsumed into three GRCs prior to the 2001 general election. The GRCs which absorbed Cheng San GRC were Ang Mo Kio GRC, Pasir Ris–Punggol GRC and Aljunied GRC due to redrawing of electoral districts by the Elections Department.
