Pritam Singh (born 2 August 1976) is a Singaporean politician, author, and lawyer who has been the Secretary-General of the Workers' Party since 2018, and Leader of the Opposition since 2020.

Singh was elected Secretary-General of the Workers' Party on 8 April 2018 as part of a leadership renewal, succeeding Low Thia Khiang.

Subsequently, Singh was appointed as the first de jure Leader of the Opposition by Prime Minister Lee Hsien Loong.

[14][16] Singh joined the Workers' Party while completing a juris doctor degree at the Singapore Management University, citing its "level-headedness and leadership" as his primary motivator.

The team included the party's secretary-general Low Thia Khiang, chairwoman Sylvia Lim and members Chen Show Mao and Faisal Manap.

They faced the team from the incumbent People's Action Party (PAP), which was led by Foreign Affairs minister George Yeo.

[22] The results of the 2020 general election saw Singh, together with Sylvia Lim, Faisal Manap and former NCMPs Gerald Giam and Leon Perera, being re-elected to represent the Aljunied GRC constituents, with an increased share of the vote of 59.95%, defeating the PAP team that received 40.05%.

Following the 2020 general election in which the Workers' Party won ten seats, Prime Minister Lee Hsien Loong decided to formally designate Singh as Leader of the Opposition, and said that he would be "provided with appropriate staff support and resources" to carry out his new parliamentary appointment role.

[28] On 19 March 2024, two years after the police originally initiated investigations into his conduct before the COP, the Public Prosecutor charged Singh in the State Courts with two counts of lying to a parliamentary committee, under Section 31(q) of the Parliament (Privileges, Immunities and Powers) Act 1962.

[29][30] On April 17, it was reported that Singh had appointed Andre Jumabhoy and Aristotle Emmanuel Eng Zhen Yang as his defence counsel.
