No Platform, in the UK, is a form of student boycott where a person or organisation is denied a platform to speak. The British National Union of Students (NUS) established its No Platform policy in April 1974. Like other No Platform policies, it asserts that no proscribed person or organisation should be given a platform to speak, nor should a union officer share a platform with them. The policy traditionally applies to entities that the NUS considers racist or fascist, most notably the British National Party, although the NUS and its liberation campaigns have policies refusing platforms to other people or organisations. The policy does not extend to students' unions who are part of NUS, although similar policies have also been adopted by its constituent unions.
