Low Thia Khiang

On 30 April 2020, he suffered a head injury from a fall at his home and was hospitalised at Khoo Teck Puat Hospital. He was discharged on 21 May.

Low announced at his party's 60th anniversary dinner that he would not be contesting for the post of Secretary-General for the 2018 party elections and would step down to renew leadership in WP after being at its helm for 17 years. Low formally stepped down as WP chief on 8 April 2018. Chan Chun Sing, the Minister for Trade and Industry, subsequently praised Low at a Parliament sitting on 15 May 2018 for the role he played in Parliament, acknowledging him as "a fellow Singaporean and very much part of Team Singapore", and that "(w)hile (the PAP) may not always agree with (Low's) perspectives or methods, (the PAP) nevertheless appreciate(d) his efforts to work together to build a better Singapore.

In the 2016 Workers' Party Central Executive Committee (CEC) elections, Low's position of Secretary-General was contended by fellow Aljunied MP Chen Show Mao. This was the first time Low was challenged for the post since he took it up in 2001. Low retained his seat with 61 votes, to Chen's 45. Chen remains in the CEC as a member.

At the 2015 general election, Low and his team won and retained their seats in Aljunied GRC. However, the team's votes share decreased to 50.96%, a drop of 3.76%, with a narrow margin of 1.9% (2626 votes). As the margin was within the 2% range, there was a recount. This was Low's sixth continuous win as an elected opposition MP (four in Hougang SMC and two in Aljunied GRC). He has been one of few elected opposition MPs to successfully defend a GRC.

Low is one of six elected opposition MPs in Singapore's 13th Parliament.

At the 2006 general elections, Low won his fourth straight term for the Hougang constituency. He received 13,987 of the votes cast, a 62.74 per cent victory margin which is an increase of 7.74% from the last general election in November 2001. His opponent from the People's Action Party, Eric Low, received 8,306 votes.

He was the Secretary-General of the Workers' Party of Singapore from 27 May 2001 to 8 April 2018 and the leader of the opposition from 2 November 2006 to 8 April 2018 in Parliament. He had been a Member of Parliament (MP) since 1991, representing Hougang Single Member Constituency from 1991 to 2011, and Aljunied Group Representation Constituency since 2011. He is the MP responsible for the Bedok Reservoir–Punggol Division within Aljunied GRC.

On 27 May 2001, Low became the Secretary-General of the Workers' Party, replacing J. B. Jeyaretnam. He was re-elected again as the MP for Hougang at the 2001 general election.

Low was re-elected as the MP for Hougang SMC at the 1997 general election, his second election victory in Hougang.

Between 1997 and 2011, Low and Chiam were the only elected opposition Members of Parliament (MP) in Parliament. At the 2011 general election, both Low and Chiam left their seats in Hougang and Potong Pasir SMC respectively to contest in Aljunied GRC and Bishan-Toa Payoh GRC respectively, risking that there will be no elected opposition MPs in parliament. Low's gamble pays off as he led the Workers' Party to a historic breakthrough in the election, with a victory in Aljunied GRC. The win marked the first time ever that an opposition party had won a GRC, bringing an additional five Workers' Party MPs into Parliament. His previous seat in Hougang SMC was retained by his party member, Yaw Shin Leong.

In 1991, Low, as the Workers' Party's Assistant Secretary-General, won the single-member constituency (SMC) of Hougang in the 1991 general election and entered Parliament. In 1992, Low was appointed by Prime Minister Goh Chok Tong as a member of the Cost Review Committee. After a year of intensive study, Low decided to produce his own independent report as he had a different perspective from the other members of the committee.

In 1988, Low represented the WP in a televised debate with the PAP government on proposals to create an elected Presidency for Singapore, during which he engaged Ong Teng Cheong and Lee Hsien Loong, who later became the President and Prime Minister of Singapore respectively. In the general election later that year, Low, together with Gopalan Nair and Lim Lye Soon, contested the Group Representation Constituency (GRC) of Tiong Bahru against only the PAP and finished second with 42.2% of the vote.

Low joined the Workers' Party (WP) in 1982, and was subsequently appointed as its Organising Secretary. At the 1984 general election, he was the election agent for the party's secretary-general, J. B. Jeyaretnam, in his successful campaign to win Anson constituency.

Low studied at Lik Teck Primary School and Chung Cheng High School before he attended Nanyang University, where he majored in Chinese language and literature, and government and public administration. In 1981, he completed a Bachelor of Arts (Honours) in Chinese studies at the National University of Singapore. In 1982, he completed a diploma in education. He worked as a teacher for a few years before starting his own business.

Low first met Han Mui Keow while they were students at Chung Cheng High School in 1973. They were married in 1982 and had two sons and a daughter. He is a Buddhist.
