Sembawang Group Representation Constituency

Since its creation in 1988, the GRC has been held by the People's Action Party and it has been uncontested at every general election until the general election in 2006. The Group Representation Constituency was led by former Deputy Prime Minister and PAP chairman Tony Tan until his retirement in 2006, who would later go on to serve as the seventh President of the Republic of Singapore (2011 and 2017), and also was led by Transport Minister Khaw Boon Wan (who's also the Coordinating Minister for Infrastructure and the fifth PAP chairman) from 2006 to 2020 together with his co-led Education Minister Ong Ye Kung. Ong Ye Kung has joined the team in 2015 General Elections.

The largest number of voters meant that the constituencies are split into Holland–Bukit Panjang GRC (now Holland–Bukit Timah GRC) in 2001 (Bukit Panjang division), Nee Soon GRC in 2011 (Chong Pang and Canberra divisions) and Marsiling–Yew Tee GRC in 2015 (Marsiling and Woodgrove divisions). Nee Soon GRC had handed back Simpang planning area to Sembawang GRC to allow further development in 2015. With the growing development of both Sembawang and Yishun new towns, the next election saw Yishun portion of Gambas, as well as Simpang hiving off to Nee Soon GRC.

In the 2020 general election, Minister of Transport, Khaw Boon Wan retired from politics, he has been succeeded by Poh Li San and Education Minister Ong Ye Kung succeeded him as Minister of Transport.
