There is growing unrest within Jeremy Corbyn's campaign team over his approach to dealing with issues of concern to the Jewish community, the JC can reveal.

One well-placed source within his team said that the unwillingness to deal "head-on" with these issues had come from Mr Corbyn himself.

The reluctance, according to the source, was because the frontrunner in the Labour leadership campaign was "partly casual about Jewish concerns, partly [because he knows] hostility to 'Zionist neocons' plays well to his constituency".

Media interest in Mr Corbyn's association with Holocaust deniers, antisemites and other extreme figures has grown in the past three weeks since the JC posed a series of questions for him to answer.

Another senior Corbyn campaign member indicated this week that the issues raised by this newspaper were not being taken seriously by Mr Corbyn and his team and said some within the team have grown concerned at the Islington North MP's reluctance to speak in more depth publicly about the Jewish community's concerns.

"This comes from Corbyn himself," the source said.

Despite an invitation last week from the JC for Mr Corbyn to write an article addressing antisemitism on the left and among his supporters, he refused.

A spokeswoman blamed "time management" for the decision on Tuesday.
