A comedian has pulled out of a student charity fundraiser at the University of London in January where he had agreed to give his time free, after he was asked to sign a contract banning him from causing offence in twelve separate areas.

The contract sent by politics student Fisayo Eniolorunda, event organiser for the Unicef on Campus society to comedian Konstant Kisin required him to follow the society’s no-tolerance policy regarding racism, sexism, classism, ageism, and ableism, along with homophobia, transphobia, biphobia, xenophobia, Islamophobia, anti-religion and anti-atheism. The contract also stated that “It does not mean these subjects cannot be discussed but it must be done in a respectful and non-abusive way”. However Mr Kisin, 35, who was born in the Soviet Union took the ban as undermining his freedom of speech, something that he said happened in the Soviet Union, and declined to perform “on a point of principle”.
