The Labour Party has opened an inquiry into allegations of anti-Semitism and intimidation at its Oxford University Labour Club, after the club’s co-chairman quit and alleged a history of anti-Jewish attitudes.

Labour’s national students group announced the enquiry, and a Labour spokesman said the party backed it, The Guardian reported on Wednesday.

“Following recent allegations of anti-Semitic behaviour and intimidation at Oxford University Labour Club (OULC), Labour Students have launched an immediate investigation and the Labour party welcomes and supports this action,” the spokesman said.

“If complaints are made about any individual member of the Labour party, the party will take robust action to deal with any anti-Semitic behaviour.”

OULC co-chairman Alex Chalmers resigned Monday night in protest over the society’s endorsement of an upcoming Israel Apartheid Week.

In a sharply worded statement, he claimed that “a large proportion of both OULC and the student Left in Oxford more generally have some kind of problem with Jews.”
