Lee Hsien Loong (IPA: LEE SYEN-LONG; 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 became the Senior Wrangler at Cambridge in 1973, and graduated in 1974 with a Bachelor of Arts with first class honours degree (later promoted to Master of Arts by seniority) in mathematics and a diploma in computer science (now equivalent to a master's degree 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 on choosing to pursue the path of politics over mathematics, saying 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.
