Following its dissolution in 1988, Jalan Kayu was incorporated into the new Cheng San Group Representation Constituency.
The People's Action Party had held the ward by a narrow margin of 571 votes in the 1984 election.
Note: Madai Puthan Damodaran Nair was offered the first and only Non-constituency Member of Parliament (NCMP) seat, only to reject it.
[1] 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.
Notes: The then incumbent Tan Cheng Tong from People's Action Party had attempted to seek another term, but this time round he joined Barisan Sosialis instead and win the election, despite his votes' share was slashed by nearly half.
