Labour-supporting students backed Hamas terrorists’ efforts to kill Jews, sang about rockets over Tel Aviv, and discussed “an international Jewish conspiracy,” it has been claimed.

Jewish students at Oxford University revealed a list of what they say are examples of antisemitism within the university’s Labour club.

The claims were made on Tuesday night, 24 hours after Oxford University Labour Club (OULC) co-chair Alex Chalmers quit, citing what he said was “a problem with Jews” in the club.

Mr Chalmers resigned after OULC endorsed Israel Apartheid Week – a week of events runs annually by anti-Israel activists.

In a statement on Tuesday evening the JSoc said: “OULC has become increasingly dominated by the radical student left in recent weeks and months.

"This has been accompanied by a series of antisemitic statements and incidents. Following Alex Chalmers’s resignation, other OULC members have approached Oxford University Jewish Society with reports of these incidents.”

The allegations include one claim that an OULC member was disciplined for organising a group of students to harass a Jewish student and shout "filthy Zionist" at her.

Another alleged: “One member, then on committee, stated that all Jews should be expected to publicly denounce Zionism and the state of Israel, and that we should not associate with any Jew who fails to do so.”

Earlier on Tuesday, the OULC's co-chair Noni Csogor said: "We take allegations of antisemitism in the club very seriously.”

The OULC is one of the largest and most prestigious student Labour clubs in the country. Its former members include the party's ex-leaders Ed Miliband and Michael Foot.

On Wednesday morning, Labour's deputy leader Tom Watson posted a tweet which suggested he would be asking party chiefs to look into the episode.
