In 1968,
Whampoa Constituency was formed by carving out of
Kallang Constituency. In 1988, it was renamed as
Whampoa Single Member Constituency as part of Singapore's political reforms. It existed for another term until 1991 when it was abolished and divided into
Kampong Glam,
Jalan Besar and
Toa Payoh Group Representation Constituencies. In 2011, Whampoa Single Member Constituency was recreated by carving out from
Jalan Besar Group Representation Constituency (GRC) as Jalan Besar GRC was dissolved and was replaced by Moulmein–Kallang and Tanjong Pagar GRCs respectively.
Heng Chee How contested as a solo PAP candidate in the newly formed Whampoa SMC and won with 66.1% of the vote against the
National Solidarity Party's Ken Sun. This was despite a national swing against the PAP. It was later merged back to the revived Jalan Besar GRC again in the
2015 Singaporean general election. ==Member of Parliament==
