In 1933, several factional representatives, including Tạ Thu Thâu, Nguyễn Văn Tạo of the ICP [later to be labour minister in Hanoi] and the anarchist Trinh Hung Ngau, regrouped around charismatic figure of
Nguyễn An Ninh, and took the initiative of legally opposing the colonial regime in the Saigon municipal elections of April–May 1933. They put forward a common "Workers' List" and briefly published a newspaper (in French to get around the print restrictions on Vietnamese),
La Lutte (The Struggle) to rally support for it. In spite of the restricted franchise, two of this Struggle group were elected (although denied their seats), the independent (later Trotskyist) Tran Van Thach and Nguyễn Văn Tạo. In 1934 the
La Lutte the collaboration was revived on the basis of a formal Party-Oppositionist
entente: "struggle oriented against the colonial power and its constitutionalist allies, support of the demands of workers and peasants without regard to which of the two groups they were affiliated with, diffusion of classic Marxist thought, [and] rejection of all attacks against the USSR and against either current." In the March 1935 Cochinchina Colonial Council election candidates supported by
La Lutte obtained 17% of the votes, although none were elected. Two months later in the Saigon municipal elections four of six candidates on a joint "Workers' Slate," including Tạ Thu Thâu and Nguyễn Văn Tạo, were elected, although only Tran Van Thach as the ostensible non-communist was allowed his seat. At the end of 1935, unwilling to enter into a further accommodation with the "Stalinists, " the October Group of Hồ Hữu Tường, Lu Sanh Hanh and of
Ngô Văn (the chronicler of the Trotskyist struggle in later exile) formed the core of the League of Internationalist Communists for the Construction of the Fourth International (
Chanh Doan Cong San Quoc Te Chu Nghia--Phai Tan Thanh De Tu Quoc). The League maintained a "complete system of clandestine and legal publications" including its own weekly "organ of proletarian defence and Marxist combat",
Le Militant (this carried Lenin's Testament with its warnings against Stalin, and Trotsky's polemics against the
Popular Front), topical pamphlets in both French and Vietnamese (including Ngô Văn's denunciation of the
Moscow Trials) and an agitational bulletin,
Thay Tho (Wage and Salary Workers). After
Le Militant was suppressed, from January 1939 the League/the Octobrists began clandestinely publishing
Tia Sang (The Spark). The title,
The Spark, may have been a reference to
Tia Sang (the Spark) group in Hanoi, and suggests an organisational connection. In 1937–38, this northern group had put out a weekly,
Thoi Dam (Chronicles), with a call to workers and peasants to set up "unified people's committees in the struggle for rice, freedom and democracy." Octobrists are reported to have been active in labour organising in Hanoi,
Haiphong and
Vinh. While the
Stalinists urged respect for the law to the peasants who had begun to agitate in a violent manner against direct and indirect taxes and for a reduction in rents, the League's call for "action committees" was met with widespread arrests. The "first trial of the
Fourth International" opened in Saigon on 31 August 1936. Following publicised testimony of their torture and maltreatment, Lu Sanh Hanh and seven of his comrades received moderated sentences of 6 to 18 months. In Saigon, with a renewed upsurge culminating in the summer of 1937 in general dock and transport strikes, the tide on the left seemed to be running in favour of the Trotskyists. Judging by the frequency of the warnings in the clandestine Communist press against Trotskyism the influence of the oppositionists in the organised unrest was "considerable" if not "preponderant." Tạ Thu Thâu and Nguyễn Văn Tạo came together for the last time in the April 1937 city council elections, both being elected. Together with the lengthening shadow of the Moscow Trials (obliging the Party loyalists to denounce their erstwhile Trotskyite colleagues as "the twin brothers of fascism"), growing disagreement over the new PCF-supported Popular Front government in France ensured a split. The
La Lutte group had entered its own Popular Front known under the name of the Indo Chinese Congress Movement (Phong-tiao-Dong-duong-Dai-hoi) with the bourgeois Constitutionalist Party, in order to draw up demands relating to the political, economic and social reforms that were to be presented to the new government in Paris. But the leftward shift in the French national Assembly in Thâu's view had not brought meaningful change. He and his comrades continued to be arrested during labour strikes, and preparations for a popular congress in response to the government's promise of colonial consultation had been suppressed. Colonial Minister Marius Moutet, a Socialist commented that he had sought "a wide consultation with all elements of the popular [will]," but with "Trotskyist-Communists intervening in the villages to menace and intimidate the peasant part of the population, taking all authority from the public officials," the necessary "formula" had not been found. Thâu's motion attacking the Popular Front for betraying the promises of reforms in the colonies was rejected by the PCI faction and in June 1937 the Stalinists withdrew from
La Lutte. Labour unrest culminated in the general strike of 1937 that included workers in the arsenal at Saigon, of the Trans-Indo Chinese Railway (Saigon-Hanoi), the Tonkin miners and the
coolies of the rubber plantations. Their demands were for an eight-hour day, trade union rights, rights of assembly, a free press, etc. The government resorted to repression and in October the Indochinese Congress Movement was itself dissolved. Trotskyist and Stalinist papers that had sometimes been able to appear in the Vietnamese language were banned once more, and the labour legislation remained a dead letter. ==The Workers and Peasants slate vs. the Democratic Front==
