SINGAPORE - Ang Mo Kio GRC's Inderjit Singh said he will not contest the upcoming general election.

Mr Singh announced his decision to step down in a Facebook post at 9.04pm on Friday, following the release of the Electoral Boundary Review Committee's report earlier in the day.

His Kebun Baru ward, which falls under Ang Mo Kio GRC, had been redrawn into Nee Soon GRC.

"I thank the residents of Kebun Baru and Ang Mo Kio for the support they gave me during this time and for the confidence and trust they placed in me," wrote Mr Singh.

The 55-year-old veteran has been serving as an MP in Ang Mo Kio since 1997.

Ang Mo Kio GRC, headed by Prime Minister Lee Hsien Loong, is one of two remaining six-member GRCs.

Analysts say one new face that could replace Mr Singh is food-supply company Foodtraco Supplies executive director Henry Kwek, who joined Mr Singh in Kebun Baru several months ago. Mr Kwek, 39, was branch secretary at Law and Foreign Minister K. Shanmugam's Chong Pang ward.

Two others who are seen as potential candidates in Ang Mo Kio are Temasek Polytechnic's School of Design deputy director Darryl David, 45, and colorectal surgeon Koh Poh Koon, 42.

Dr Koh was a PAP candidate during the Punggol East by-election in 2013, where he lost to the Workers' Party Lee Li Lian.
