The end of PSRM (1990)

The last socialist party to exist in Malaysia, Parti Sosialis Rakyat Malaysia, reverted their name to Parti Rakyat Malaysia in 1990 before merging with Parti Keadilan Rakyat in 2003.

Formation of PSM (1990–1998)

In 1991, several grassroots based organisations working with the urban and rural poor in Malaysia started to form an alliance. In 1994, they staged a massive Labor Day demonstration at the heart of Kuala Lumpur surprising many people. The last major demonstration called by the working class in the capital city was in the 1970s.

In 1995, these grassroots organisation who already had their strong support among the plantation workers, the urban poor, and industrial workers formed an alliance and the idea for a political party to represent the aspirations of the poor and the marginalised was mooted. The election results in 1995 hastened this process and after years of discussion and consolidations, it was finally agreed that a party with socialist ideology was needed to liberate the masses from their current conditions.

With this in mind, the groups took more than two and the half years to draft the party's constitution, which was ready by the end of 1997. After further consultation with the masses, on 1 May 1998, the new party known as the Socialist Party of Malaysia was officially put for registration.

1999 general election

In 1999, the party decided to contest in the year's general election. Since PSM was not registered, it had to contest under some other party's logo. In 1999, the candidates contested under a Democratic Action Party's ticket. The main intention was to popularise the party. The party lost in its seat but managed to reduce the opponent's majority by 10,000 votes.

2004 general election

PSM candidates fielded for the 2004 general election.

In the 2004 general election, PSM had to contest on the logo of another party, Parti Keadilan Nasional (now known as Parti Keadilan Rakyat).

2008 general election

Three PSM members contested in the 2008 general election under the Keadilan ticket and one as an independent. Two of these candidates won PSM's first ever political seats.

Candidate Michael Jeyakumar Devaraj won PSM's first ever federal parliamentary seat by defeating then president of Malaysian Indian Congress and long-serving Minister of Works Samy Vellu in Sungai Siput. PSM's president Mohd Nasir Hashim won the Kota Damansara seat in the Selangor state legislative assembly.

Although S. Arutchelvan lost, PSM's election campaigning resulted in an increase in membership in Semenyih. The remaining member who contested Jelapang as an independent was M. Sarasvathy.^[3]

2013 general election

The two PSM incumbents, Michael Jeyakumar Devaraj and Nasir Hashim, recontested their seats in the 2013 general election under Keadilan. Jeyakumar retained the PSM's parliamentary seat of Sungai Siput but PSM president Nasir lost the Kota Damansara state seat to a United Malays National Organisation (UMNO) candidate, after a PAS member split the opposition vote.

Another two PSM members, S. Arutchelvan and M. Sarasvathy, also recontested the same seats but this time under the PSM ticket.

2018 general election

For the 2018 general election, PSM competed in their largest turnout (~2% of available Parliamentary + State seats); this consisted of five federal constituencies and 14 state constituencies. All PSM candidates for this general election competed under PSM name and logo, as opposed to the previous elections.^[4] Unlike in previous elections, the then chairman Nasir Hashim announced that he was not running in the 2018 election.

PSM did not succeed in winning any seats this election and lost the Sungai Siput parliamentary seat it held since 2008.

2023 state election

On 15 July 2023, PSM and Malaysian United Democratic Alliance (MUDA) announced a political alliance for the 2023 state elections as the "third choice" for voters "who are unhappy and bored with the politicians now and want to protest."^[5]
