# The 1924 Zinoviev Letter was a forgery that helped swing a British election

**Verdict: Contradicted.** The letter is almost certainly a forgery. A 1999 Foreign Office historian's report concluded it was fabricated by anti-Bolshevik emigres and leaked to the press, with some British intelligence officers complicit in circulating it.

Category: Government & Intelligence · Era: Interwar era · First circulated: 1924 · Believed by: Widely accepted by historians as a forgery; the identity of the forgers remains contested.

## Summary
Four days before Britain's October 1924 general election, the Daily Mail splashed a letter supposedly from Moscow's Comintern chief Grigory Zinoviev, ordering British communists to prepare for revolution. It stoked a Red Scare and is often blamed for helping bury the first Labour government. The document was a forgery. The open questions are who wrote it and how much of British intelligence knew.

## The claim
That a letter dated 15 September 1924, purportedly signed by Grigory Zinoviev of the Communist International, was a genuine directive to the Communist Party of Great Britain to agitate for revolution and subvert the British armed forces, and that its publication days before the 1924 general election exposed a real Soviet plot rather than a planted forgery.

## Origin and timeline
- 1924-01: Ramsay MacDonald forms Britain's first Labour government, a minority administration, and moves to normalise relations with the Soviet Union, negotiating Anglo-Soviet treaties that included a proposed loan to Moscow.
- 1924-09-15: The date borne by the letter later attributed to Grigory Zinoviev, chairman of the Comintern's executive committee, addressed to the Central Committee of the Communist Party of Great Britain and urging agitation, infiltration of the armed forces, and pressure to ratify the treaties.
- 1924-10: A copy reaches the Secret Intelligence Service (SIS/MI6) through its station in Riga, Latvia. SIS circulates it to the Foreign Office as genuine; officials including Desmond Morton vouch for it despite private doubts.
- 1924-10-25: The Daily Mail publishes the letter under alarmist headlines, four days before polling. The Foreign Office simultaneously releases a stiff note of protest to the Soviet charge d'affaires, Christian Rakovsky, which lends the document an air of official authenticity.
- 1924-10-29: Britain votes. The Conservatives under Stanley Baldwin win a landslide, taking 413 seats; Labour falls to 151 and leaves office after less than a year. Rakovsky and Moscow denounce the letter as a 'clumsy forgery.'
- 1924-11: Two Cabinet committees examine the letter's authenticity (the records survive at The National Archives as CAB 27/254). The new Conservative government treats it as genuine; MI5's own analysis privately doubted it.
- 1966: A Sunday Times 'Insight' investigation reports the claim of Irina Bellegarde that her husband and other White Russian emigres forged the letter, naming figures tied to an anti-Bolshevik network in Berlin and the Baltic.
- 1998: Foreign Secretary Robin Cook commissions Gill Bennett, Chief Historian of the Foreign and Commonwealth Office, to investigate the affair using British and, for the first time, Russian archives.
- 1999: Bennett's report is published. It concludes the letter was almost certainly a forgery, most likely by anti-Bolshevik emigres in the Baltic, leaked to serve domestic political ends, with some SIS officers aware of and complicit in its circulation.

## The evidence, claim by claim
- Claim: The Zinoviev Letter was a genuine directive from the Comintern to British communists.
  Evidence: Not supported. No original ever surfaced; every version in circulation was a copy. The Soviet government and Comintern denied it immediately and consistently, and the surviving Comintern archives, opened to Gill Bennett in the 1990s, contain no trace of it. Historians overwhelmingly treat it as a forgery, even while noting its language echoed real Comintern rhetoric of the period, which is precisely what made a fake plausible.
- Claim: It was fabricated by White Russian emigres opposed to the Anglo-Soviet treaties.
  Evidence: This is the leading explanation, though not proven to the last name. The trail points to anti-Bolshevik Russian emigres operating between Berlin and the Baltic, with the forgery routed through Riga. Two Berlin-based emigres, Alexis Bellegarde and Alexander Gumansky, have been named as the likely forgers. Bennett's 1999 report judged the forgery almost certainly the work of such circles, while cautioning that 'it is impossible to say' with certainty who physically wrote it.
- Claim: British intelligence officers knew it was suspect and passed it on anyway.
  Evidence: Substantially supported. SIS obtained the letter via its Riga station and vouched for it to the Foreign Office as authentic. Officers including Desmond Morton harboured private doubts yet treated it as genuine. Bennett's report found that some in SIS were aware of the letter's dubious provenance and were complicit in leaking it to the Conservative press and party, sharing a conviction that MacDonald's government was a danger to the country.
- Claim: The letter was deliberately timed and leaked to damage Labour before the election.
  Evidence: The circumstances fit a leak, not a coincidence. It reached the Daily Mail and Conservative Central Office and appeared four days before polling, alongside a Foreign Office protest note that made the government appear to accept it. The Foreign Office decided to publish against MacDonald's wishes, and the note went to Rakovsky before the Prime Minister had approved it. What the record does not establish is a single, centrally directed conspiracy: Bennett found opportunistic collusion by like-minded individuals rather than one coordinated plot.
- Claim: The letter is what cost Labour the 1924 election.
  Evidence: Overstated, and historians now push back on it. MacDonald's minority government had already fallen on a confidence vote over the Campbell case, and Labour's national vote actually rose by around a million from the previous year. The Conservative landslide owed much to the collapse of the Liberal vote under Britain's first-past-the-post system. The letter deepened the Red Scare and embarrassed MacDonald, but the tidy story that it single-handedly sank Labour is a simplification the evidence does not carry.
- Claim: The British government eventually admitted the letter was fake.
  Evidence: In effect, yes, through its own historian. The 1999 report by the Foreign Office's Chief Historian, commissioned by the Foreign Secretary and drawing on secret intelligence files, concluded the letter was almost certainly forged. That is as close to an official acknowledgement as the affair has produced, even though the report stopped short of naming the forgers or alleging a formal state conspiracy.

## Why people believe it
- Because the forgery was plausible on its face: it mimicked genuine Comintern language, and the Soviet Union really was funding foreign communist parties, so the fake sat convincingly on top of a real pattern of Soviet activity.
- Because an official-looking apparatus lent it weight. When the Foreign Office issued a formal protest note the same day the letter appeared, the state seemed to be treating it as real, which is hard for ordinary readers to discount.
- Because the affair really did involve intelligence officers behaving improperly, so the instinct that 'something was covered up' is not paranoia. The 1999 report confirmed genuine complicity in leaking the document, which keeps the wider story alive.
- Because it became a founding grievance for the British left: a template of the 'establishment' and a hostile press conspiring to bring down a Labour government, endlessly reinvoked whenever later scandals seem to rhyme with it.

## Open questions
- Who actually forged the letter is still not settled. The evidence points strongly to anti-Bolshevik Russian emigres working between Berlin and Riga, and names such as Alexis Bellegarde and Alexander Gumansky recur, but Gill Bennett concluded in 1999 that it remains impossible to say with certainty who wrote it. The physical original was never produced, and the chain of copies frustrates any final attribution.
- How far the complicity inside SIS extended, and whether any senior figure directed it rather than merely tolerating it, is unresolved. Bennett found that some intelligence officers knew the letter was suspect and helped it reach the press and the Conservative party, but she stopped short of finding a single, centrally organised conspiracy, and not every operational file could be published under British secrecy rules. The gap between individual bad faith and institutional plot is where the argument still sits.
- Whether the letter changed the 1924 result at all remains genuinely debated. Labour was already out of office and heading for likely defeat, its vote rose rather than collapsed, and the decisive shift was the implosion of the Liberals. Historians disagree on how much the Red Scare moved votes as opposed to simply dominating the final days of a campaign Labour was probably going to lose regardless.
