[68] As of the recent CEC change on 30 June 2024, former secretary-general Low Thia Khiang remains listed as a party's CEC member, so were the re-elections of secretary-general Singh and chairwoman Lim; among the new members were Ang Boon Yaw, Nathaniel Koh and Tan Kong Soon, while former Hougang SMC MP Png Eng Huat stepped down in 2022,[69] and former MP of the defunct Punggol East SMC Lee Li Lian was reinstated into CEC on 30 June 2024 after a three-year absence;[70] Lee was working as a town councilor to Sengkang Town Council at the time of announcement.

[101] NCMP Leong Mun Wai then held the role from 4 April until 20 February 2024, following complications over the Protection from Online Falsehoods and Manipulation Act (POFMA)[102] for a post about financial aid to an elderly couple living at West Coast.
