What’s going on with the higher education ‘free speech’ debate?

The question of whether free speech at British universities is being threatened has been fraught with controversy in recent months. Sam Gyimah, as well as previous Universities Minister Jo Johnson, have accused safe spaces, no-platforming, and trigger-warnings as impeding free expression. However, many campaigners have pointed to the Prevent legislation as a greater hindrance to freedom of speech, arguing that the policy aimed at preventing ‘radicalisation’ may be used as a guise for universities to refuse controversial or unpopular speakers a platform.
