We're not even on our first go around this University "free speech" game. A previous Conservative government put anti-no-platform clauses into the Education (No. 2) Act 1986[0] during the previous 'politically correct' moral panic. The practical effect is to require universities themselves to make sure that there are facilities for speakers etc. that their students union refuses to host for political or moral reasons. These duties are still in force.
