Stephanie Tan, a central executive committee member of the Progress Singapore Party (PSP), announced her departure from the party citing differences over its direction. Tan, who contested Pioneer Single Member Constituency (SMC) in the 2025 general election, said, "It has been such a fulfilling journey and while I remain hopeful to continue contributing to Singapore, it will no longer be through PSP due to differences in opinion in the direction of the party" [1].

Tan joined PSP as a volunteer in August 2023 and was co-opted into the party’s central executive committee in July 2025 following a leadership renewal after the election [1, 2, 3]. She ran in Pioneer SMC against incumbent Patrick Tay of the ruling People’s Action Party (PAP), securing 34.55% of the vote in one report and approximately 34.6% in another, marking the party’s best single-member constituency performance in GE2025 [1, 2, 3, 4]. Before her departure, Tan was active in community activities across western Singapore [1, 2, 3].

The People’s Power Party (PPP), another opposition party, also announced leadership changes after GE2025. Founder and secretary-general Goh Meng Seng and chairman Derrick Sim stepped down following the party’s failure to secure adequate support in the election [1, 2, 3, 4]. All PPP candidates lost their election deposits of S$13,500 by falling below the 12.5% vote threshold [4]. Goh accepted full responsibility for the party’s performance, saying, "I bear full responsibility for the party’s showing" [4].

William Lim, the newly appointed PPP secretary-general, stated the party’s revised focus will be on "improving the daily lives of Singaporeans rather than engaging in confrontational politics" [4]. The PPP also announced its completion of central executive committee renewal and appointed a new party chief in July 2025 [1, 2, 3, 4].

In GE2025, PSP fielded 13 candidates across six constituencies but experienced a drop in vote share compared to the 2020 elections [1, 2, 3]. Meanwhile, the ruling PAP won 87 of 97 seats contested [4].

The recent changes were publicly announced on July 6, 2025, shortly after the election results were finalized [1, 2, 3]. These leadership adjustments mark a recalibration among Singapore’s opposition parties following their 2025 general election performances.
