The National Union of Students has been forced to apologise after omitting Judaism from a survey on religion - just months after making the same mistake.
The form - which was sent out across the UK - offered 11 options including 'Muslim', 'Christian' and 'Spiritual' but failed to mention the country's fifth-largest faith.
It has sparked a furious backlash with Twitter users accusing the NUS of 'forgetting Jewish students again' after it emerged that the organisation made the same error just months ago.
In July it sent out a religious survey which missed out Judaism sparking a series of complaints from furious students.
In a grovelling video posted on her Twitter profile, NUS president Shakira Martin (pictured) said: 'The first time it happened, I could tweet and say sorry. But the second time it's unacceptable'
'People know that I'm a person that if I do something wrong, I'll be the first one to say sorry, and I'm hoping that people out there will know that I'm being genuine.
'I'm so angry. Being president and being accountable sometimes can be really difficult.'
She added: 'I sincerely apologise. I think that's what's wrong with politicians and student politicians – people are scared to say sorry.
'I'm sorry. I'm sorry if anyone felt like they weren't welcomed or that they were pushed out – genuinely that is not my intention, across the whole organisation.'
The survey was revealed on Twitter by NUS delegate Tom Harwood, who said the organisation had a 'long way to go' regarding its 'attitudes to Jewish students'.
One user replied: 'The NUS turns into a bigger and bigger joke every year shocking organisation when will it be stopped.'
Peter Murphy added: 'This is truly shocking. It is either an embarrassing oversight or blatant anti-Semitism. Either way NUS should make a full and unequivocal apology.'
The NUS has faced allegations of anti-Semitism in the past with former president Malia Bouattia being widely criticised for branding Birmingham University as 'something of a Zionist outpost'.
When challenged over the remarks in September 2016, she refused to apologise for them.
She said at the time: 'I would certainly review my language and would definitely want to explain the political context which I was discussing.
'I absolutely was not saying the things that it has been interpreted as, if you will...'
Ms Bouattia also defended 'safe space' and 'no-platform' policies in universities amid widespread concerns they are curtailing free speech.
