Jeremy Corbyn was today accused of making a direct comparison between the Israeli occupation of the West Bank and the Nazi takeover of Europe.
A video has surfaced of him making the ‘appalling’ comment at an event in 2013, when he was still a backbencher.
The statement appears to flout the globally-accepted definition of anti-Semitism which says it is anti-Semitic to compare the Israeli government with the Nazis.
But Labour said Mr Corbyn was referring to all occupations in the Second World War, not just that of Adolf Hitler’s regime.
The Labour leader is facing mounting pressure to come back from his summer holiday to get a grip on the scandal tearing his party apart.
The Board of Deputies of British Jews said Mr Corbyn must stop being ‘invisible’ and ‘come out of hiding’ and get back to Westminster.
While ex Scottish Labour leader Jim Murphy took out a full page advert in a Jewish newspaper apologising for the scandal and laying the blame with the Labour leader.
It comes a week after Mr Corbyn was forced to apologise after being exposed for appearing at an event in 2010 where other speakers compared Israel to the Nazis.
Labour Friends of Israel tore into Mr Corbyn over the remark, saying: ‘The Labour party’s once proud record on fighting racism and the protection of British Jews from anti-Semitism is being sacrificed to protect Jeremy Corbyn’s reputation.’
The video was posted on the Twitter account of The Golem, who collates examples of anti-Semitism.
Earlier this week the same account published a 2011 video of Mr Corbyn apparently questioning Israel’s very right to exist.
In an interview with Iranian state TV, the then backbench MP said that the view that Israel had a right to exist was an example of ‘bias’ at the BBC.
This appears to contravene the International Holocaust Remembrance Alliance definition which states it is anti-Semitic to ‘deny the Jewish people their right to self-determination’.
The latest video shows Mr Corbyn making a speech at an event hosted by the Palestinian Return Centre.
He said: ‘The West Bank is under occupation of the very sort that is recognisable by many people in Europe who suffered occupation during the Second World War with the endless roadblocks, imprisonment, irrational behaviour by the military and the police.’
Last night Jennifer Gerber, director of Labour Friends of Israel, said: ‘Earlier this week, we discovered that Jeremy Corbyn engaged in wild conspiracy theories questioning Israel’s right to exist.
‘Today, it is revealed he drew comparisons between conditions in the West Bank and the Nazi occupation of Europe.
‘It is increasingly clear that his opposition to adopting the IHRA definition in full appears to be overwhelmingly driven by his own appalling past statements.
‘The Labour party’s once proud record on fighting racism and the protection of British Jews from anti-Semitism is being sacrificed to protect Jeremy Corbyn’s reputation.’
It is not the first time the Labour leader has been accused of having compared the actions of the Israeli government with the Nazi regime.
In a rally in 2010 he said the siege of Gaza had lasted longer than those of Leningrad and Stalingrad.
A Labour spokeswoman said: ‘Jeremy was describing conditions of conditions of occupations in World War Two in Europe, of which there are multiple examples, not comparing the Israeli state to Nazis.’
It comes as Mr Murphy has today taken out a full page advert in a Jewish newspaper apologising for the anti-Semitism scandal.
He said he took the dramatic step of paying for the slot in the Jewish Telegraph because he could not stand silent as his party ‘turned its back’ on Jews.
The ex Cabinet minister launched a blistering attack on the Labour leader in the advert, accusing him of not doing ‘nearly enough’ to kick anti-Semites out of the party.
The astonishing attack comes as Jewish leaders furiously demanded that Mr Corbyn ‘come out of hiding’ from his holiday by the seaside and tackle the crisis.
In the advert, Mr Murphy branded Mr Corbyn and his allies ‘intellectually arrogant, and emotionally inept’ and said they have ‘deliberately turned their back on British Jewry’.
He added: ‘Today there’s a small, but growing minority of anti-Semitic conspiracy theorists amongst the membership of the Labour Party.
‘Jeremy Corbyn is not doing nearly enough to throw out the anti-Semites found within grassroots and online Labour.’
He laid the lame for the crisis squarely at the feet of the Labour leader and his supporters.
Mr Murphy, who lost his seat in 2015, said: ‘No party leader has the right to hatter the relationship between British labour and British Jewry.
‘The Jewish community and everyone else who is offended by Labour’s stance are being asked to accept quarter-baked platitudinous Labour apologies for the “upset that has been caused”.
‘Instead what’s needed urgently is Labour action against the sickening anti-Jewish racism that is the actual cause of the offence in the first place.’
Meanwhile, the Board of Deputies of British Jews president Marie van der Zyl warned the Labour leader ‘you cannot lead through invisibility’ and said that he must come back form holiday to get a grip on the crisis.
Writing in Jewish News, she said: ‘He is clearly just hoping it will go away. I’ve got some bad news for him – unless he does what he needs to do, it won’t.’
She added: ‘I call on Jeremy Corbyn to come out of hiding and do the right thing.’
The Labour leader has been accused of purposely ignoring the racism which festers among some of his supporters.
While Labour MP Dame Margaret Hodge – who lost family members in the holocaust – says Mr Corbyn and his allies are using the row to try to purge the party of his moderate critics
It emerged yesterday that Mr Corbyn has been given a month to back down over the anti-Semitism row or face losing the backing of his powerful allies in Momentum.
The grassroots organisation helped install and keep Mr Corbyn in power.
The Labour leader has rebuffed demands by Jewish leaders and many of his own MPs to fully adopt the international definition of anti-Semitism – a move they insist is crucial if the party is to finally get on top of the scandal.
The party has adopted some of the International Holocaust Remembrance Alliance’s definition.
But crucially it has not included several of the examples they use to illustrate it – including that Israel’s existence as a state is a racist endeavor.
Mr Corbyn has now been told by Momentum he must formally sign up to the definition at a crunch party meeting in early September, the Politico website reports.
While the GMB trade union – one of the UK’s biggest trade unions and a major force in Labour – has also come put to publicly demand the same.
If he refuses they could pull support for him – triggering what could be the biggest crisis in his leadership since the failed coup against him in the summer of 2016.
