Kakis, grab your kopi-O siew dai and sit down. If you talk about Singapore political drama in recent years, few stories come close to the sudden and sensational fall of former Speaker of Parliament Tan Chuan-Jin.

Once viewed as a potential future Prime Minister or senior Cabinet leader, his career came crashing down in July 2023 in a matter of days. Here is the full breakdown of how TCJ rose to fame—and how it all unraveled.

1. The Meteoric Rise: The “Golden Boy” of the PAP

Tan Chuan-Jin’s journey in public life began with a textbook “scholarly elite” path:

• Military Elite: He served in the Singapore Armed Forces (SAF) for 24 years, rising to the rank of Brigadier-General before stepping down to join politics.
• The 2011 Political Debut: He entered politics during the landmark 2011 General Election as part of the five-member PAP team in Marine Parade GRC alongside former PM Goh Chok Tong.
• Fast-Tracked to Cabinet: Within months, he was inducted into the PAP’s highest decision-making body (the CEC). He was appointed Senior Minister of State, then became full Minister for Manpower (MOM) in 2014, and later Minister for Social and Family Development (MSF) in 2015.
• The People’s Politician: Unlike standard, stiff politicians, TCJ built a massive personal brand. He was charismatic, active on social media, shared his personal photography, loved running, and projected a deeply empathetic, down-to-earth persona that resonated with younger Singaporeans.

2. The Shift to Speaker of Parliament (2017)

In 2017, TCJ stepped out of the Cabinet to become the 10th Speaker of Parliament after Halimah Yacob resigned to run for President.

While moving out of the Cabinet meant stepping off the core 4G leadership track, TCJ remained extremely popular. As Speaker, he was known for running parliamentary sittings with a lighthearted touch, maintaining a strong social media presence, and actively championing social causes and volunteerism.

3. The Early Cracks in the Armor

Even during his peak popularity, there were occasional missteps:

• The 2015 Cardboard Collector Controversy: While serving as MSF Minister, TCJ posted on Facebook after visiting elderly cardboard collectors in Jalan Besar. He suggested that some collected cardboard not out of financial hardship, but as a “form of exercise and activity”. The post sparked widespread online backlash for being out of touch, though he later clarified his intent was not to generalize.

4. July 2023: The One-Two Punch Downfall

The dramatic downfall happened in July 2023 in two rapid, devastating blows:

Strike 1: The “Hot Mic” Incident

In early July 2023, a recording from an April parliamentary sitting surfaced online. A hot microphone caught Speaker TCJ muttering the expletive “fing populist”* under his breath after Workers’ Party MP Jamus Lim finished a speech on lower-income support.

The clip went viral, drawing intense criticism over his neutrality and decorum as Speaker. TCJ issued a public and private apology to Jamus Lim.

Strike 2: The Resignation and Extramarital Affair

Just days later on July 17, 2023, Prime Minister Lee Hsien Loong announced that both Tan Chuan-Jin and fellow PAP MP Cheng Li Hui had resigned from Parliament and the PAP.

In a press conference, PM Lee revealed:

1. The pair had been involved in an inappropriate extramarital affair.
2. PM Lee had first learned about the relationship after GE2020 and had counselled both of them.
3. In February 2023, TCJ offered his resignation, but PM Lee instructed him to ensure his ward was taken care of first and strictly demanded that the affair end.
4. When PM Lee discovered in mid-2023 that the affair was still ongoing, combined with the hot-mic incident, TCJ’s position became completely untenable, leading to his immediate exit.

The Takeaway

Tan Chuan-Jin’s story remains one of the most stark reminders in Singapore’s political history: reputation takes a decade to build, but only a moment to break.

Going from a highly praised Brigadier-General and Cabinet Minister to resigning in disgrace over personal conduct, his fall demonstrated the unforgiving nature of political scrutiny in Singapore—and how quickly public trust can dissolve when high standards of propriety are breached.
