Lee Hsien Loong ( ; born 10 February 1952), also known by his initials LHL, is a Singaporean politician and former military officer who has served as the Senior Minister of Singapore since 2024, having previously served as the third Prime Minister between 2004 and 2024. He also served as the secretary-general of the governing People's Action Party (PAP) between 2004 and 2024. As a Member of Parliament (MP), he has represented the Teck Ghee division of Ang Mo Kio Group Representation Constituency (GRC) since 1991, having previously represented Teck Ghee Single Member Constituency (SMC) between 1984 and 1991.
Born and raised in Singapore during British colonial rule, Lee is the eldest son of Singapore's first prime minister, Lee Kuan Yew. He graduated from Trinity College, Cambridge, in 1974 with first class honours in mathematics and a Diploma in Computer Science with distinction (equivalent to a first-class master's in computer science). He served in the Singapore Armed Forces (SAF) between 1971 and 1984, and attained the rank of Brigadier-General, completing a Master of Public Administration degree at Harvard Kennedy School in 1980. Lee discharged from the SAF in 1984 to enter politics.
Lee served in several cabinet roles under Lee Kuan Yew and Goh Chok Tong before succeeding the latter to becoming prime minister in 2004. Early in his term, his government enacted a five-day work week and extended maternity leave. He proposed building two integrated resorts to boost tourism, which resulted in the Marina Bay Sands and the Resorts World Sentosa. After the Great Recession, he managed the national economic recovery and introduced reforms to increase non-constituency members of parliament. He later led the response to the COVID-19 pandemic and the associated recession and recovery. In 2022, Singapore became the only Southeast Asian country to sanction Russia following the Russian invasion of Ukraine. His government also legalised male same-sex sexual activity by repealing Section 377A, which was already an unenforced law. In 2024, Lee stepped down and was succeeded by Lawrence Wong, who appointed him as a senior minister in his cabinet.
Lee maintained political continuity and technocratic governance while expanding social safety nets and public housing to further reduce inequality. However, critics noted his high level of control over political discourse and the use of defamation lawsuits against journalists and bloggers such as Roy Ngerng. These actions were often viewed as a way of discouraging dissent. Additionally, the introduction of the Protection from Online Falsehoods and Manipulation Act in 2019 raised concerns about a chilling effect on free speech. He also faced a public dispute with his siblings regarding their late father's house at 38 Oxley Road. Throughout his tenure, Lee remained the highest-paid head of government globally.
Early life Lee Hsien Loong was born at KK Women's and Children's Hospital in Singapore on 10 February 1952, during the time when Singapore was a British colony. He is the eldest child of Lee Kuan Yew and Kwa Geok Choo and the patriline grandson of a retired storekeeper-turned-salesman, Lee Chin Koon (1903–1995) and Chua Jim Neo (1905–1980), a chef. His mother has ancestry from Tong'an District and Longhu while his father has ancestry from Dabu County in China.
Education Lee was educated at Nanyang Primary School and Catholic High School—where he played clarinet in the school band, and National Junior College before he was awarded the President's Scholarship and Singapore Armed Forces Overseas Scholarship in 1971 by the Public Service Commission (PSC) to study mathematics at Trinity College, University of Cambridge.
He was Senior Wrangler at Cambridge in 1973, and graduated in 1974 with a first class Bachelor of Arts degree in mathematics and a diploma in computer science (with distinction). His college tutor, Denis Marrian, later described Lee as "the brightest mathematician he had admitted to the college". Béla Bollobás said that Lee "would have been a world-class research mathematician", but his father did not realise this and persuaded Lee to leave the field. In an interview prior to Lee's resignation as prime minister in 2024, Lee revealed that he did not regret choosing politics over mathematics, declaring that he "had the responsibility to come back to Singapore, be part of Singapore, and do what [he] could to help the country to succeed", which was "the right thing to do".
He subsequently went on to complete a Master of Public Administration degree, becoming a Mason Fellow at Harvard University's John F. Kennedy School of Government in 1980.
Military career Lee joined the Singapore Armed Forces (SAF) in 1972, and served as a commissioned officer between 1974 and 1984, and held various staff and command posts, including Director of the Joint Operations and Plans Directorate, and Chief of Staff of the General Staff.
He also attended the United States Army Command and General Staff College at Fort Leavenworth in 1978.
Lee rose quickly through the ranks in the Singapore Army, becoming the youngest brigadier-general in Singapore's history after his promotion in July 1983 at the age of 31.
Notably, he was put in command of the rescue operations following the Sentosa cable car disaster. Lee served as commanding officer of the 23rd Battalion Singapore Artillery in the Singapore Army before he left the SAF in 1984 for politics.
Early political career During the 1980s, Lee was regarded as the core member of the next batch of new leaders in the People's Action Party (PAP) leadership transition that was taking place in the mid-1980s, as Lee Kuan Yew had declared that he would step down as prime minister in 1984. Following the 1984 general election, all of the old Central Executive Committee members except Lee Kuan Yew resigned on 1 January 1985.
Lee was first elected Member of Parliament for the Teck Ghee SMC in 1984, at the age of 32.
In 1985, he was appointed Minister of State for Trade and Industry, and Minister of State for Defence. He chaired the government's economic committee, which recommended changes to established government policies to reduce business costs, foster longer-term growth and revive the Singapore economy, which was experiencing a recession at the time. The committee's recommendations included reductions in corporate and personal taxes and the introduction of a consumption tax.
In 1986, Lee was appointed Acting Minister for Trade and Industry. In 1987, he became a full member of the Cabinet as Minister for Trade and Industry and Second Minister for Defence.
PAP Youth Committee In March 1986, First Deputy Prime Minister Goh Chok Tong discussed the question with Lee on encouraging younger Singaporeans to join the party. Goh was firm that the proposed committee should attract only the right kinds of members, ruling out material rewards as an incentive. The proposed youth wing was to encourage the improvement of the system from within, which would give new members a stake in the country's future. Lee later said the establishment of the youth wing reflected concerns by the leadership that the lack of an official channel to engage with the younger generation might lead them to vote for opposition parties and potentially bring the PAP government down. The youth wing was an official "tailor-made" mechanism to allow dissenting opinions to be heard.
Lee was the first chairman of the PAP Youth Committee upon its establishment, the predecessor to Young PAP.
Deputy Prime Minister (1990–2004) Ministerial duties On 28 November 1990, Goh Chok Tong succeeded Lee Kuan Yew as prime minister. Lee Hsien Loong was made one of two deputy prime ministers, along with Ong Teng Cheong. He continued to serve as the minister for trade and industry until 1992, when he was diagnosed with lymphoma. He subsequently relinquished his ministerial position and underwent three months of chemotherapy, though he continued to be a deputy prime minister during his illness. The chemotherapy was successful, and his cancer has gone into remission.
Lee was appointed chairman of the Monetary Authority of Singapore (MAS) in January 1998, and in 2001 he was made the finance minister. To ease the growing budget deficit due to falling tax revenues from cuts in corporate and personal income taxes and other factors such as the Iraq War and SARS outbreak, Lee proposed on 29 August 2003 to raise the GST from three per cent to five per cent, a change that took place in January 2004.
Lee initiated several amendments to render requirements for Singapore citizenship less restrictive, notably for foreign-born children of Singaporean women. The changes were made after repeated pleas from MPs and the Remaking Singapore Committee.
Visit to Taiwan On 10 July 2004, Lee visited Taiwan, an island claimed by the People's Republic of China (PRC) that has been ruled by the Republic of China (ROC) since 1945. The Singapore government maintains a policy of neutrality in the Cross-Strait relations between the two sides despite having severed diplomatic relations with the Republic of China on 3 October 1990 in favour of the People's Republic. To continue facilitating this policy when Lee becomes Prime Minister, Lee believed it to be important for him to "personally feel for the situation" in Taiwan and made the trip going to Taiwan. Ministry of Foreign Affairs officials advised that any visit to Taiwan by an incumbent prime minister would be diplomatically impossible, hence the trip was planned a month before Lee assumed the premiership and in his capacity as a private citizen, not as a government minister or as the head of government, with the PRC embassy informed on 9 July 2004.
On the same day's afternoon, the PRC government summoned the Singapore ambassador in Beijing and urged the cancellation of Lee's trip, citing the likelihood of Chen Shui Bian's administration in Taiwan exploiting the trip as a diplomatic coup and using it to promote the independence of Taiwan, with the PRC claiming that Singapore was making a "historical error" for the trip. Then-Foreign Minister S. Jayakumar replied to the PRC counterpart of him Li Zhaoxing that the ROC government had been asked to keep the visit low-profile and that it would proceed as planned.
The PRC later retaliated by cancelling several visits by high-ranking PRC officials to Singapore and delaying planned signing ceremonies, hinting that free trade negotiations would also be pushed back. The matter was further complicated and magnified when Taiwanese media headlined the visit and portrayed it as a diplomatic breakthrough, which raised tensions with the PRC. The Singapore government later published the full records of the discussion with the Chinese embassy in Singapore's local media.
On 28 August 2004, in his first National Day Rally speech and as prime minister, Lee criticised some Taiwanese political leaders over their lack of understanding over the shifting balance of power across the Taiwan strait and Taiwan's international position in their zeal for Taiwanese independence; and he criticised Taiwanese for capitalising on his private visit. He reiterated the reasons for the visit and said that Singapore's decision to stand firm on its vital interests had earned it international respect. Relations were eventually mended when Lee met Hu Jintao at the APEC Economics Leaders' Meeting on 19 November 2004, which signified the end of the dispute.
Prime Minister (2004–2024) 2004–2006: First term
On 12 August 2004, Lee succeeded Goh Chok Tong as prime minister and relinquished his chairmanship of the Monetary Authority of Singapore to Goh Chok Tong whom had Lee sworn in at the Istana. As prime minister, Lee also became chairman of the People's Association.
