Barisan Sosialis (BS), also known as the Socialist Front, was a left-wing political party in Singapore. It was formed on 29 July 1961 and was officially registered on 13 August 1961 by the leftist faction of the People's Action Party (PAP) which had been expelled. The prominent founding members of BS were Lee Siew Choh and Lim Chin Siong. It was a major political force and one of the biggest opposition parties in Singapore during the 1960s. It listed its main objectives as "eradicating colonialism", establishing a "united independent and democratic Malayan nation" comprising the Federation of Malaya and Singapore, and "introducing an economic system to promote prosperity and stability in society."
As the PAP consolidated its power during the 1960s, the PAP-led government cracked down on BS, characterising it as a communist front as part of the geopolitical climate of the Cold War. In 1963, as part of Operation Coldstore, over 100 opposition leaders, including Lim, were arrested in preventative and indefinite detention under the Internal Security Act (ISA) with support of the British and Malayan governments. The arrests severely weakened BS, with boycotts by BS MPs to Parliament leading to more arrests throughout 1966 and 1967, most notably Chia Thye Poh.
BS would fully boycott the 1968 elections, cementing the PAP's political dominance. This followed a series of political crackdowns which the government justified as security measures to prevent a communist revolution; for instance, when BS shifted away from parliament in 1966, Chia himself declared that the means of the struggle would be "street demonstrations, protests and strikes". However, these actions were also criticised as political suppression, as BS members did not publicly agitate for communism or subversion during their time as an elected opposition. Despite contesting subsequent elections, BS never recovered from its heyday and most of its members joined the Workers' Party (WP) in 1988. An application for dissolution was denied and the party became dormant. In 2025, it was officially deregistered alongside 13 other parties for a failure to prove its existence while inactive.
History
Background Since its formation, the PAP was divided into two main factions: the Fabian, conservative, and technocratic faction led by Lee Kuan Yew, and the revolutionary socialist and Marxist faction led by Lim Chin Siong. The common ground of anti-colonialism and independence of Singapore was the basis for the co-operation between the two factions. Differences in their mass bases also encouraged such co-operation. During the early years, the left-wing faction mainly commanded support from the Chinese masses, rural people and trade unions, while support for Lee's faction was mainly found in the English-educated community. With the support of the working class, the PAP won the third-most seats in the 1955 election and formed the main opposition. In 1959, with the support of the trade unions, the PAP won the election and formed the Government under Lee. However, the two factions were ideologically and politically different in nature. During its formative years, the left-wing members already showed their dissatisfaction with the policies carried out by Lee Kuan Yew and his failure to fulfill his promises to help secure the release of the left-wing political detainees. Finally, the contentious issue of merger with Malaysia triggered the split within the PAP.
On 27 May 1961, Tunku Abdul Rahman, Prime Minister of the Federation of Malaya, suggested the creation of a new Malaysia state consisting of the Federation of Malaya, Singapore, Sarawak, North Borneo and Brunei. The reactions towards merger within the PAP were divided. The merger with Malaysia was supported by the Lee Kuan Yew faction as a means of assuring Singapore's future security and prosperity, while opposed by the left-wing faction as the merger was seen as an attempt to "wipe out the left-wing forces in Singapore" (Interview with Dr Lee Siew Choh).
The rupture within the PAP was widened by the Hong Lim and Anson by-elections in 1961. Displeased with the PAP government's refusal to abolish the Internal Security Council (ISC), refusal to back down the merger plan and refusal to release the remaining political detainees, the PAP left-wingers abandoned support for their own candidates in favour of Ong Eng Guan (in Hong Lim) and David Marshall (in Anson), which led to the PAP's defeat in the two by-elections.
After the 1961 by-elections, the left-wing faction planned to oust Lee from the party but they worried that their actions would cause the British to hold up plans for Singapore's independence. As a result, the left-wingers had a meeting with Lord Selkirk, the British Commissioner-General at Eden Hall, which was later known as the "Eden Hall Tea Party". At the meeting, the left got assurance from Selkirk that Britain was committed to independence and would not intervene militarily to maintain control after the overthrow of Lee's government.
Formation On 20 July 1961, Lee Kuan Yew called an emergency meeting of the Legislative Assembly to vote on a motion of confidence in the Government. Twenty-seven assemblymen voted for the government and twenty-four, including thirteen of PAP left-wingers, either abstained or voted against the motion of confidence. The thirteen PAP left-wingers who abstained from voting were then expelled from the PAP. The expelled members, including Lim Chin Siong, Sidney Woodhull and Fong Swee Suan, then proceeded to form an opposition party, the Barisan Sosialis. After the split, 35 branch committees out of 51 and 19 of 23 paid organising secretaries of the PAP went over to BS.
BS was officially inaugurated on 17 September 1962, with Lim Chin Siong as its secretary-general and Dr Lee Siew Choh as chairman. Its founding slogan was 'genuinely full internal self-government' through merger with Malaya and it shared the same aim with the PAP-'the creation of an independent, democratic, non-communist, socialist Malaya'. The main objectives of the new party were presented in following four statements:
To eradicate colonialism and set up a united national independent state comprising the Federation of Malaya and Singapore To establish a democratic Government of Malaya based on universal adult suffrage of all those who are born in or owe their allegiance to Malaya To bring into being an economic system that will endure a prosperous, stable and just society To mobilise all sections of the people for the building of a Malayan nation
Merger issue
While BS did not oppose the merger with Malaya, it campaigned vigorously against the PAP government's merger terms with the Federation of Malaya. According to the merger terms agreed by the PAP government, Singapore would retain its autonomy in education and labour at the expense of the rights of Singapore citizens and seats in the new Federal Parliament. BS wanted Singapore citizens to automatically become Malayan citizens with proportional representation in the Federal Parliament. At the end, the PAP government advocated that a referendum should be held to test popular support for the merger.
The Referendum Bill on the merger incorporated proposals and amendments from BS, David Marshall, Ong Eng Guan and SPA-UMNO. Three offered options A, B, C respectively proposed by the PAP, David Marshall and the SPA-UMNO. However, BS appealed to voters to cast blank votes on the referendum stating that no option correctly expressed BS's thoughts and the three options would "sell out Singapore". This move had been anticipated by the ruling PAP government, as the insertion of a clause that stated that all blank would be counted as a vote for the option that wins the most votes if there was no outright majoritySingapore, 1 September 1962: Integration with Malaya Direct Democracy or that blank votes would be counted as Option A.Singapore National Referendum Ordinance 1961.
The Referendum on Merger was held on 1 September 1962, and the results were 95.82% voted for Option A proposed by the PAP. As the blank votes are considered as Option A, BS's plan was defeated.
Operation Coldstore
Tunku Abdul Rahman was worried about the impact of Singapore's leftist influence in a unified Malaysia. He demanded that Singapore's political opposition be arrested as a condition of merger. The PAP was hesitant about the arrests as they could damage the PAP's popularity in Singapore. However, the Brunei Revolt of 8 December 1962 gave the PAP a 'heaven sent opportunity' to justify the arrests. The BS's open support of the Brunei revolt gave the PAP an excuse that the arrests were to prevent possible communist subversion and safeguard the security and safety in Singapore.
On 2 February 1963, the ISC launched a crackdown against leftists and their supports. Under the action, code-named Operation Coldstore, 113 people including political, trade unionists and student leaders who had shown support for the Brunei Revolt were detained. Among those detainees, half of them were BS central leaders.
Operation Coldstore had substantially weakened the Barisan as most of its key personnel had been detained. According to Matthew Jones, "the Barisan never recovered from the combined effects of the outcome of the referendum result and the 'Coldstore' detentions." Jones also highlights that numerous Barisan leaders and members were bogged down with lawsuits and its followers were "demoralised". In addition, Tan Jing Quee mentions that "the two main pillars of the left-wing movement in Singapore, the Barisan Sosialis and SATU, were decapitated," following Operation Coldstore.
On 22 April 1963, Lee Siew Choh and remaining BS activists launched the "City Hall Battle". They marched from the BS's headquarter in Victoria Street to the steps of City Hall to protest the mass arrests in February and presented a petition to the Prime Minister in protest against the 'ill treatment' of the detainees. The protest was put down and seven party leaders including Lee Siew Choh were arrested.
1963 general election
After Operation Coldstore and ensuing protests, major cadres of BS were detained or put on long trials. With Secretary-General Lim Chin Siong detained since February 1963, Lee Siew Choh served as both Chairman and de facto party leader during the election campaign. These events severely diminished the strength of BS, which prevented the party from effectively taking part in the 1963 general elections, and the party was eventually defeated in the elections. The 1963 elections ended with a clear victory of PAP winning thirty-seven of the fifty-one seats. BS won thirteen, and the remaining seat fell to Ong Eng Guan who contested under the banner of the United People's Party. Lim Huan Boon became the de facto Leader of the Opposition.
After the elections, the Malaysian Government took a series of actions to further debilitate BS. On Malaysia Day on 16 September 1963, the security authorities decided to launch two further crackdowns on the "left-wing" extremists. In those September and October operations, "some fifteen leaders of the Communist United Front" were rounded up. Some student activists from Nanyang University were soon arrested for alleged subversive activities. In late August 1963, seven trade unions under Singapore Association of Trade Unions (SATU) controlled by the BS, were served notices by the Government to show cause why they should not be deregistered. On 30 October, the seven unions which were supposed to close down were eventually struck off the register. In October, the government dissolved two of BS's most effective ancillary associations, The Singapore Rural Residents' Association and Singapore Country People's Association.
