Respect MP George Galloway is suing a students' union after he was banned by the group for being a "rape denier".
The National Union Of Students (NUS) passed the motion against the Respect MP last week, despite a last-ditch plea from a member of his office that Galloway's views are "widely held on the left of the political spectrum".
Galloway, a vocal Julian Assange supporter, made headlines across the nation in August after he posted a podcast addressing the sex crime allegations against the Wikileaks founder.
Speaking to a camera, he said: "Even taken at its worst, if the allegations made by these two women were true, 100% true, and even if a camera in the room captured them, they don't constitute rape.
"It might be really sordid and bad sexual etiquette, but whatever else it is, it is not rape or you bankrupt the term rape of all meaning."
Following the comments he was denounced by his then party leader, Salma Yaqoob, and his comments were branded "offensive and deeply concerning" by Rape Crisis.
An NUS spokesperson told The Huffington Post UK the union believes "there is a culture of undermining rape victims and rejects attempts to glorify, joke about or dismiss rape".
The NUS added: "The motion passed yesterday confirms that NUS shall not offer a platform to speakers who are rape deniers or apologists, or support events where such individuals speak.
"NUS will campaign to tackle attitudes on campus that trivialise sexual assault or seek to blame survivors, and instead promote a better understanding of consent."
A member of Galloway's office confirmed the Bradford West MP would be suing the NUS but would not comment further until the writ is served or the union apologises.
The MP tweeted:
The NUS said it had not received any contact from Galloway's lawyers.
