Flat-Pack Leninism: Why Mike MacNair can’t save the Weekly Worker from Moreno’s dead end
Trotsky named the plague. Mandel diagnosed the mechanism. The Communist Platform enacted both.
TL;DR Trotsky in 1940 named two kinds of factionalist: the one compelled by genuine political rupture, and the one who lives on factionalism as a permanent condition. The first is a necessity. The second is a plague. Mike MacNair’s Revolutionary Strategy offers a detailed constitutional model for a healthy party and no theory of how a healthy party becomes sick. The Communist Platform’s entry into and departure from Left Unity — pre-assembled, vote lost, dissolved — enacted the plague with textbook precision. The Weekly Worker’s current campist line on Ukraine is not a coincidence; it is what happens when the machinery that was supposed to guarantee political democracy is repurposed to insulate a line from challenge.
In February 1940, writing to James Cannon during the factional crisis in the American SWP, Trotsky drew a distinction that has not aged. There are, he wrote, two kinds of factionalist. One lives on factionalism, has no other political existence, generates and sustains splits as a way of life. The other wages a factional struggle under compulsion, because a political line requires it, and dissolves the faction when the political issue is resolved. The first category is a plague, Trotsky said. The second is a necessity. The distinction matters because it cuts through the perennial confusion, on the British left and elsewhere, between the principled defence of a minority position and its pathological reproduction. (In Defence of Marxism, Pathfinder 1990, p.155.)
The plague form has a theory. Or rather, it acquires a theory after the fact: the constitutional dress that gives organisational practice the appearance of principled method. It is this theoretical cover that makes the Weekly Worker — the paper of the CPGB-PCC — an instructive case, rather than simply an irritating one.
Seventeen years before Trotsky wrote that letter, he had identified the mechanism that makes the plague possible. In The New Course (1923), written in the context of the Soviet party’s bureaucratisation, he named apparatus displacement: the process by which the centre of gravity in a revolutionary party shifts from political authority to organisational machine, from the living debate of its membership to the managed outputs of a leadership caste. ‘Leadership takes on a purely organisational character.’ The phrase should be read slowly. Not leadership that organises, but leadership as organisation: the substitution of procedural management for political argument as the source of authority. Once that shift is complete, the apparatus acquires a self-interest in its own reproduction that is formally independent of any political line it might happen to hold.
Mike MacNair’s Revolutionary Strategy (2008) reconstructs party theory from the pre-1914 Second International tradition. It is a serious work and has been taken seriously, including by people who have good reason to disagree with it. It discusses party degeneration, too: there are careful pages on Soviet bureaucratisation, on Trotsky’s bureaucratic centralism in the 1939-40 US faction fight, on what went wrong. But this historical diagnosis and the positive model sit in entirely separate registers that never meet. When MacNair arrives at his own prescriptions, on pp.154-155, he offers a party ‘democratic-republican in its organisational character’: elected and recallable officials, freedom of information, public factions ‘with their own press, organisation and membership.’ Not once in those prescriptions does he ask how a healthy party becomes an unhealthy one. The party MacNair designs arrives, in effect, flat-packed: all components present, assembly instructions clear, no theory of what happens to furniture nobody actually lives with. The New Course is not cited anywhere in the book. The omission is structural: the most directly relevant Trotskyist text on apparatus displacement is simply absent, relocated to the history chapters, where it stays.
There is an irony in this worth sitting with. Point 11 of MacNair’s theses proposes that the workers’ party should express political difference through ‘public factions with their own press, organisation and membership.’ The Weekly Worker enacts a grotesque literalism of exactly this prescription. The Communist Platform in Left Unity had its own press, its own organisation, its own membership obligations: flat-packed and ready for deployment into any broad formation that would have it. What MacNair describes as the form through which principled political difference should be expressed, the Weekly Worker has converted into the permanent condition of its political existence. The prescription and the pathology have become indistinguishable. That is what happens when a party model has no theory of how good forms become bad ones.
Which brings us to a document that has not, until now, been available in English. In September 1977, Ernest Mandel produced an extended internal polemic against Nahuel Moreno’s PST, written for the Fourth International and circulated originally in Spanish. Red Mole is producing the first English translation of this text, and it illuminates the present argument with a precision that no secondary account can replicate.
Mandel’s target in 1977 was a specific organisational pathology he identified in the way Moreno was building the PST and preparing its adhesion to the FI. The PST’s militants, Mandel wrote, were being enrolled in revolutionary Marxism ‘not on the basis of adhesion to the program of the movement as a whole, and in a spirit of loyalty to the organization as a whole, but after intensive factionalist preparation prior to the adhesion itself.’ Mandel calls this ‘entirely contrary to the spirit of democratic centralism.’ Pre-adhesion factionalist preparation: a bloc is assembled before the debate opens, members are educated into a line before they have encountered the full range of argument, and the faction arrives at the broader organisation with its positions already locked. Democratic centralism’s guarantee, the possibility of all members informing themselves objectively and all tendencies expressing themselves on equal terms, is negated at the point of entry.
The CPGB-PCC enacted this pathology with considerable precision when it entered Left Unity in 2013. It did not join Left Unity and then develop a position. It arrived with the Communist Platform pre-assembled: a bloc already constituted, constitutional demands already drafted, interventional strategy already determined. The permanent tendency was declared formally on 8 February 2014. It was dissolved on 20 February 2016. Not because Left Unity collapsed, not because the political questions it was addressing had been resolved: because the Communist Platform’s motion was defeated. An organisation entered, inserted a pre-formed constitutional apparatus, lost a vote, and left. That is not the necessity Trotsky describes. It is the plague.
The named architects of this intervention are Ben Lewis, Stan Keable, and Yassamine Mather, among others. They are named because what they did was political, in the sense that it was deliberate, principled on their own account, and publicly defended. The Weekly Worker, the CPGB-PCC’s publication, characterised Left Unity’s broader programme as ‘Keynesian platitudes’. The characterisation is revealing. It is not wrong that Left Unity’s programme was limited. But the correct response to a limited programme in a broad formation is to argue within it, to win people through the experience of struggle, to raise the level of political discussion through sustained engagement. What it is not is to arrive with a prepared platform, push for constitutional adoption, and depart when the vote is lost. The second method is not political intervention; it is, at best, factional colonisation, and at the worst, a performative hobby.
All of this might remain merely historical, a case study in British left pathology, were it not for what follows from it. An organisation that has replaced political analysis with procedural apparatus cannot self-correct. The mechanism for correction in a healthy democratic-centralist organisation is the political mobilisation of the membership against a line: someone reads the situation differently, makes the argument, wins a debate. But if the constitutional machinery exists precisely to protect the line, if factions are the primary mode of engagement rather than the exception compelled by genuine rupture, then no such correction is possible. The apparatus has become autonomous.
The CPGB-PCC’s current line on Ukraine is worth examining carefully, because the Weekly Worker is not a paper that bans debate. Articles appear. Letters run. Contributors have published positions that diverge from the editorial centre of gravity. Taras Bilous has been cited; Ukrainian socialist arguments have circulated in its pages. And yet: Britain should leave NATO, arms should stop, Russia is not imperialist. The line holds. That is precisely the point. Debate that exists within an editorially managed framework, where the apparatus determines what counts as the mainstream and what counts as a minority contribution, is not the same thing as political accountability to the class. The Ukrainian socialist arguments are present in the paper and absent from its conclusions. Trotsky’s apparatus displacement describes exactly this: not the suppression of debate, but its digestion. The machine processes the argument and produces the same output: a decade later, the comrades are repeating the Left Unity model in Your Party.
There is a historical irony here that Mandel would have appreciated, and probably did not find amusing. The Second International model MacNair draws on produced parties with constitutional sophistication and minimal capacity for revolutionary action. The New Course was written because the Bolshevik party, the one organisation that had demonstrated the capacity for revolutionary action, was undergoing the transformation Trotsky was trying to name and arrest. The lesson of that transformation, the lesson the FI drew across decades of painful experience, is that constitutions do not make parties democratic. Cultures do. No, more precisely: the organic relationship between a party and the class it seeks to lead makes parties democratic, because it is that relationship, and not any internal mechanism, that generates the pressure for correction when a line is wrong.
Disconnect the party from the class. Substitute factional preparation for class work. Replace the nine o’clock ward-committee meeting, the early Saturday morning stall, the patient work in the trade union branch, with the permanent tendency statement, the constitutional motion, the procedural intervention. The result is an organisation that is, in Mandel’s phrase, perpetually producing factions around questions of immediate orientation, elevating tactical divergences to the status of programmatic ruptures, treating every internal discussion as a manifestation of the class struggle within the party. What Mandel warned against in 1977 became, in the Weekly Worker’s hands, a consciously elaborated method.
The question Trotsky poses in 1940 has not been answered. The plague is identifiable. The necessity, the factional struggle compelled by genuine political rupture, the minority that fights its corner and then, when the political issue is resolved, dissolves into the collective and does the work, that remains to be built. What does it look like in 2026, on a British left where Your Party is consolidating one set of bureaucratic habits and the surviving revolutionary organisations are mostly consolidating others? The plague has a theory. The necessity, for now, does not.
