Jeremy Corbyn sponsored a conference which called on the Labour Party to disaffiliate from its Jewish arm and denounced “the Zionist state as racist”, it has been claimed.

The Labour leader is listed as a sponsor on documents for the Labour Movement Conference on Palestine in 1984, which also asked the party to “recognise the PLO (Palestine Liberation Organisation) as the sole legitimate representative of the Palestinian people.”

The documents were posted online by Tony Greenstein, the Jewish founder of the Palestine Solidarity Campaign, who was suspended by the Labour Party in March.

Organised by the Labour Movement Campaign for Palestine, the Palestine Solidarity Campaign and the London branch of the Palestine Liberation Organisation, the conference called “on Labour Movement bodies to press for the disaffiliation of Poale Zion from the Labour Party.”

Poale Zion, the forerunner to the Jewish Labour Movement (JLM), had been affiliated with the party for 64 years at the time.

The JLM is currently working with the party to tackle antisemitism in Labour, following the partial publication of Baroness Royall’s inquiry into the Oxford University Labour Club.

Attendees of the 1984 event were also informed that the Labour Movement Campaign for Palestine “will fight within the Labour Movement — and the Labour Party in particular — to eradicate Zionism”.

Among the organisation’s pledges to conference participants were “opposition to the Zionist state as racist, exclusivist, expansionist and a direct agency of imperialism,” as well as “opposition to the manifestation of Zionism in the Labour Movement and the Labour Party in particular.”

The Labour Party did not immediately respond to a request for comment.
