"The Board of Trustees have decided to support the student vote in the recent Referendum."
The student union followed its counterparts at Lincoln, Newcastle and Hull in choosing to disaffiliate since Ms Bouattia became NUS president in April.
The new president has called her alma mater Birmingham University - which has one of the largest Jewish societies in the country - a “Zionist outpost,” and has also referred to the “Zionist-led media”.
It was also revealed in May by student newspaper The Tab that Ms Bouattia was found guilty of misconduct by the NUS last year over alleged antisemitism.
Nottingham and York’s student unions will now both reveal the results of their referenda on Friday, after the York SU decided to extend its voting deadline until tomorrow, to encourage more participation.
The SUs at Cambridge, Warwick, Exeter and Worcester have already voted against disaffiliation.
