Chua Chu Kang GRC

Chua Chu Kang Group Representation Constituency (Traditional Chinese: 蔡厝港集選區; Simplified Chinese: 蔡厝港集选区) is a five-member Group Representation Constituency located in the western area of Singapore.

The constituency covers the areas of Bukit Batok, Choa Chu Kang (formerly Chua Chu Kang SMC), Upper Bukit Timah, Jurong West and Lim Chu Kang.

Chua Chu Kang GRC was formerly called Hong Kah GRC, from 1988 to 2011, before the 2011 General Elections. Thus, since it was just a change of name, it would mean that all of its wards are from the former Hong Kah GRC, with the exception of Hong Kah North ward that had been crafted out to become Hong Kah North SMC after the 2011 elections.

It is divided into five wards namely, Bukit Gombak, Chua Chu Kang, Keat Hong, Nanyang and Yew Tee. In 2001, Bukit Gombak SMC was absorbed into the former Hong Kah GRC with the town council being Hong Kah Town Council.

In 2011, Chua Chu Kang was absorbed into the Hong Kah GRC and probably because of that, the Hong Kah GRC was renamed to 'Chua Chu Kang GRC'. Prior to the 2011 elections, Chua Chu Kang was one of the oldest surviving constituencies in Singapore and the only one to have both remained intact and existed before Singapore's independence, existed since 1959 when Singapore gained full self-governance from its colonial British Government.

Chua Chu Kang GRC is now led by Health Minister Gan Kim Yong, and also Ong Xiao Qi even alone.
