The University has a Students' Union, the University of Bristol Union, which claims to have the largest Students' Union building in the country. From this location, the student radio station BURST (Bristol University Radio Station) broadcasts and the student paper Epigram publishes. In terms of student life, the Union is responsible for the organisation of the annual freshers' fair, the coordination of Bristol Student Community Action, which organizes volunteering projects in the local community, and the organization of entertainment events and student societies. The current President of the union is Tobin Webb.Previous presidents have included Sue Lawley and Liberal Democrat MP Lembit Opik. There is a separate union for postgraduate students, as well as an athletic union, which is a member of the British Universities Sports Association. In distinction to the 'blues' awarded for sporting excellence at Oxford and Cambridge, Bristol's outstanding athletes are awarded 'reds'.
