Four out of five universities are actively stifling students' freedom of expression - so say the results of the UK's first free speech league table.
From sombreros to so-called "public buffoonery", research by online magazine Spiked shows the extent to which universities and student unions are attempting to curtail the actions of their students and speakers beyond the requirements of the law.
