The nomination day was on 18 August 2018.[1] The by-election set for a straight fight between PH's DAP and BN's MCA. While PAS had decided not to contest to make way for the BN candidate, just liked in the case of the Sungai Kandis by-election a month earlier.[5]
Pakatan Harapan retained the seat with a larger share of vote.[6]
This by-election marks the first time Pakatan Harapan had used their just approved common logo in an election. The then-federal opposition coalition was unable to contest the 2018 general election with their logo due to the Registrar of Societies not approving their registration in time for the election.[5] The registration was finally approved only after the election, which delivered the coalition to power.[8]
Conversely, the MCA will be using their own party logo for the first time since they joined Barisan Nasional in 1973.[5] MCA candidates have normally used the BN common logo in elections up to the 2018 general election.
Result
DAP and Pakatan Harapan's Wong Siew Ki polled 22,058 votes to MCA and Barisan Nasional's Tan Chee Teong's 3,975 votes retaining the seat for DAP and Pakatan Harapan.[6]
