Corbyn 'bent over backwards to help Jewish people', Charedim say in Sunday Times letter

It was then added that such leadership was "not recognised by the mainstream Haredi Jews."

The letter writers also suggested the "real current threat in the UK is anti-religious education policies being relentlessly pursued by Ofsted."

The education watchdog has fought a protracted battle with the strictly Orthodox community over demands that schools should teach about LGBT issues. 

Members of the Charedi community have joined protests organised by the Muslim community against Ofsted policies.

Mr Corbyn and other members of the Labour leadership have forged close relations with members of the Charedi community, in particular Mr Stern, over recent months.

But the Charedi attitude to the education issue is likely to cause Mr Corbyn problems especially with supporters from the LGBT community.

Last year, Stamford Hill activist Mr Stern tried to persuade Mayor of London Sadiq Khan to pull out of speaking at Novembers Board of Deputies dinner.

He wrote to the Mayor to ask him to withdraw as guest speaker from the dinner, arguing that the Board of Deputies did not represent the Charedi community.

But the Union of the Orthodox Hebrew Congregations, the main umbrella body for London’s Charedi communities moved to dissociate itself from Mr Stern’s efforts.

Mr Stern was also behind another pro-Corbyn letter which later drew criticism when it emerged many of the signatories did not know the exact wording before being asked to sign.

The JCtried to contact the Union to learn their view on the Sunday Times letter.
