Jewish students at Cambridge University have expressed “deep concern” after swastika graffiti and fliers defending Holocaust denier David Irving appeared on the campus.

The Nazi symbols were found daubed on a map of the university at Jesus Green, a park just north of Jesus College, last weekend.

The flyers first appeared at the nearby Sidgwick site last Friday, with reports of more being seen at Christ’s College.

They attacked the film Denial, the account of Irving’s failed libel case against Jewish historian Deborah Lipstadt, calling it “propaganda”.

Speaking to the Varsity newspaper, Cambridge University Jewish Society co-presidents Adam Goott and Alex Szlezinger said they were “deeply concerned by the recent escalation in the number of antisemitic incidents.

“We have already been in touch with the CST [Community Security Trust] and the Cambridgeshire police have been notified.” They planned to hold talks with the student union and university officials on how best to curb such incidents.

A spokesperson for the university said it had received “several reports of offensive and antisemitic materials being left at university sites. Facilities staff were alerted immediately and the flyers were quickly removed.”

Staff were conducting regular sweeps of the university premises, the spokesperson said.

A spokeswoman for Cambridgeshire police confirmed that officers had asked the city council to remove the graffiti.

She added that police were investigating the source of the leaflets, which they were treating as a possible hate crime.

A spokesperson for the Union of Jewish students described the incidents “deeply concerning”.
