West Coast GRC: MPs, Boundaries & 2025 Changes

A name change in Singapore politics often signals a fundamental shift, not a cosmetic tweak. When the West Coast Group Representation Constituency (GRC) became the West Coast–Jurong West GRC in 2025, it was a redrawing of political lines that reshaped the electoral map.

Type: Group Representation Constituency (GRC) ·
Number of MPs: 5 ·
Location: Western and central Singapore ·
Current Name: West Coast–Jurong West GRC (since 2025) ·
Previous Name: West Coast GRC (until 2025)

Six key facts on West Coast GRC and its transition to West Coast–Jurong West GRC:

What is the West Coast Group Representation Constituency?

Definition and purpose of a GRC

Singapore’s Group Representation Constituency (GRC) system requires a team of candidates—at least one from a minority community—to contest together. The West Coast GRC was one of the original five-member GRCs created in 1997, designed to ensure minority representation in Parliament (Wikipedia – GRC system).

Overview of West Coast GRC

• Covered areas including Ayer Rajah, Bukit Timah, Tanjong Pagar, and West Coast electoral divisions (National Archives of Singapore historic map)
• At the 2020 general election, the People’s Action Party narrowly defeated the Progress Singapore Party in this constituency (Channel NewsAsia analysis)
• The 2025 electoral boundary review renamed West Coast GRC as West Coast–Jurong West GRC to absorb parts of Jurong (The Straits Times coverage)

The implication: the old West Coast GRC no longer exists as a political entity, replaced by a reconfigured division that will test the PAP’s incumbency in new territory.

What are the boundaries and map of West Coast GRC?

Geographical coverage

• The original West Coast GRC encompassed Ayer Rajah, Bukit Timah, Tanjong Pagar, and West Coast divisions (National Archives of Singapore map record)
• It covered western and central parts of Singapore

Historical boundary changes

• The 2025 review moved HarbourFront and Sentosa to Radin Mas SMC (The Straits Times list)
• Dover and Telok Blangah were transferred to Tanjong Pagar GRC (The Straits Times report)
• Parts of Jurong were added to create the new West Coast–Jurong West GRC (The Straits Times explanation)

Where to find official maps

• The National Archives of Singapore holds an archived map of the original West Coast GRC (National Archives of Singapore)
• The Elections Department hosts an official 2025 map viewer at elections.data.gov.sg

The pattern: the redrawing dramatically altered the electoral landscape. Areas that once voted together now belong to different constituencies, making historical voting patterns less useful for predicting future outcomes.

Who are the members of West Coast GRC and West Coast–Jurong West GRC?

Current MPs for West Coast–Jurong West GRC

• Adrian Ang
• Alex Yam
• Alex Yeo
• Alvin Tan

All five are from the People’s Action Party (People’s Action Party official roster).

Former MPs for West Coast GRC

• Prior MPs included Chan Chun Sing (lead minister) and others from the PAP team that won in 2020 (Wikipedia list of representatives)

How does West Coast GRC differ from West Coast–Jurong West GRC?

The table below shows the key differences between the old and new constituencies. Two iterations, one pattern: the 2025 review expanded the constituency westward while trimming its southern reach.

The catch: while the number of MPs stayed the same, the composition of the electorate changed substantially. Voters from Jurong now have a voice in this GRC, while residents of Dover and Telok Blangah must look to Tanjong Pagar for representation.

What is the West Coast Town Council and its role?

Town Council responsibilities

• Manages common property and common areas in the constituency
• Provides services including cleaning, landscaping, and estate maintenance
• Operates under the purview of the West Coast–Jurong West GRC MPs (West Coast Town Council site)

Services provided

• Conservancy and estate management
• Community programs and events
• Feedback and appeal handling

Meet-the-people sessions

• Regularly scheduled by each MP at various locations within the constituency
• Residents can raise issues, seek assistance, or provide feedback
• Sessions are held weekly at different community centres (West Coast Town Council session schedule)

The trade-off: Town Councils are locally managed by the elected MPs, giving residents direct access to their representatives—but resources and responsiveness can vary between wards.

Summary: What the boundary redrawing means

For voters in the former West Coast GRC, the 2025 redrawing brought a new name, new neighbours, and a new electoral arithmetic. The People’s Action Party retains its five MPs, but the boundaries have shifted enough to make the next contest unpredictable. For Singaporeans following the political map, the change is clear: West Coast–Jurong West GRC is a freshly drawn battleground, and the outcome will test whether incumbency can withstand redistricting.
