Jalan Kayu Constituency

After the 1951 election, the present Jalan Kayu constituency constituted the majority of the Seletar ward; that ward was dissolved prior to the 1959 election, producing the Jalan Kayu ward, the then Thomson ward, and small parts of Nee Soon ward.

During the 1963 Singaporean general election, incumbent Tan Cheng Tong from People's Action Party seek another term but under Barisan Sosialis. While his vote share was slashed nearly by half, Tan managed to win the seat with a 7% majority.

Madai Puthan Damodaran Nair has contested here in every GE since the inception of this ward, with the exceptions in 1967 by-elections and 1968 elections where he stood as an independent candidate in Thomson and Farrer Park wards respectively. He had previously elected in Seletar ward, which has since evolved into this ward and also went through up and downs, from an end of almost being elected MP since the independence of Singapore in 1984 elections when he represented the Workers' Party of Singapore and subsequently offered but declined the Non-constituency Member of Parliament seat to lost his election deposit in 1963 elections when he was one of the candidate that entered into the multi-cornered fight's fray under the banner of Singapore Alliance.^[1]

In the 1984 election, the People's Action Party had held the ward by a narrow margin of 571 votes and Madai Puthan Damodaran Nair was offered the first and only Non-constituency Member of Parliament (NCMP) seat, only to reject it.^[2] The seat was subsequently offered to Tan Chee Kien, the second best performing but lost the election opposition candidate who ran in Kaki Bukit SMC under the Singapore United Front's banner as auxiliary NCMP who had also promptly declined the offer.^[3]

During the 1988 political reforms, the constituency was merged into the Cheng San Group Representation Constituency.^{[citation needed]}
