Students occupied Nick Clegg's Sheffield Hallam constituency office today, in protest against the cost of higher education.
Images posted on Twitter show the protesters holding up banners outside the Deputy Prime Minister's office.
They briefly entered the building itself but left after police arrived.
The demonstration, organised by the Free University of Sheffield, was a response to the Liberal Democrat leader's broken pledge at the last General Election to oppose any increase in tuition fees. Students can now be charged up to £9,000 a year
I wonder how he feels about having to show his face where he is not the favour of the century.
