An overwhelming 78 per cent of British Jews would prefer a no deal Brexit over the prospect of Jeremy Corbyn becoming Prime Minister, a new poll has confirmed.

Asked to decide between both scenarios as their least objectionable outcome for the UK in the coming months, just 12 per cent of respondents to the survey, conducted by the polling firm Survation for the JC, said they would rather see the Labour leader in Downing Street than exiting the European Union without a deal.

When asked separately whether they would consider voting Labour at the next general election with or without Mr Corbyn as Labour leader, just 7 per cent said they would consider supporting the party.

But in a sign that Labour could win back substantial numbers of Jewish voters if Mr Corbyn were no longer in charge, 42 per cent said they could vote for the party with a new leader.

Wes Streeting, Labour MP for Ilford North, told the JC: “I’m afraid this poll reflects what I hear on the doorstep in my own community, but seeing it so starkly presented is devastating – not least for significant numbers of Jews who clearly want to vote Labour but can’t because of Jeremy Corbyn.

“Given our very public failure to tackle antisemitism within our ranks, who can blame them?”

The clear opposition to Mr Corbyn becoming PM, even when faced with the scenario of a No Deal Brexit, is even more devastating for Labour when taking into account the previously pro-Remain sympathies of British Jews in past opinion polls.

A Survation poll carried out for the JC in May 2016, ahead of the referendum that year, revealed that 49 per cent of Jews wished to remain in the EU. Only just over a third – 34 per cent – backed Brexit, with 17 per cent stating they were undecided.

Dudley North MP Ian Austin, who quit Labour earlier this year in protest at the party’s antisemitism crisis, said: “This poll shows the shameful extent to which the Jewish community – which traditionally showed strong support for Labour – has been alienated by the racism which has poisoned the party under Jeremy Corbyn's leadership.

“Six times as many Jewish people would vote Labour with a different leader – so even if moderate MPs won't get rid of him because it is the right thing to do, you'd have thought they would at least do it for electoral reasons.”

Ahead of the 2017 general election, a Survation poll for the JC showed just 13 per cent of British Jews planned to vote Labour under Mr Corbyn.

The latest figure of seven per cent shows his popularity has dipped even further.

When age breakdown is taken into account, 57 per cent of 18-34 years old in the latest Survation poll said they would consider voting Labour without Mr Corbyn as leader.

Survation carried out the poll by questioning 766 self-identified Jewish residents aged over 18 in the UK between September 19 and October 14.

Ten per cent of those surveyed said they did not know which outcome they preferred when asked to choose between No Deal and Mr Corbyn as PM.

A Jewish Labour Movement spokesperson said: "Jews voted two-to-one to Remain, but such is the level of mistrust and antipathy towards Jeremy Corbyn, our community thinks him becoming PM a greater threat than a calamitous no deal Brexit.

“If Labour ever needed a wake-up call that its failure to tackle institutional anti-Jewish racism, this should be it. Jews shouldn't be forced to compromise their values just to feel safe as a community.”
