Sheffield students occupied Lib Dem leader Nick Clegg’s constituency office yesterday to remind the world of the Deputy PM’s ditched free education promises.

Over a dozen students from Sheffield and Sheffield Hallam universities walked into Mr Clegg’s office in the early morning supported by Unite Community members demonstrating outside.

But South Yorkshire Police were “very quick” to move in, escorting occupiers out less than an hour after the start of the protest.

Speaking from the site history student Minesh Parekh said: “We did it to remind people that it was Nick Clegg who got elected on a platform of getting rid of tuition fees and then tripled them.”

Free University of Sheffield said in a statement that students were seen as customers and education a personal investment.

“We believe that education needs to be seen as a public good which benefits society as a whole.”

The group added: “We need to remind ourselves of education’s intrinsic value. It can give us fulfilment, empowerment and a shared sense of cooperation — something which has been lost in today’s universities.”

According to campaigners, Lib Dem staff were quickly briefed that the action was peaceful and they were welcome to stay as students organised a “non-hierarchical learning space” on the premises.

But within 10 minutes three police cars showed up, one of which carrying police dogs.

“They basically just shepherded us out,” said Mr Parekh.

Despite some minor altercations and officers stopping students from flying an “offensive” banner no arrests were made.

Unite Community young member Daragh O’Neill told the Star: “We decided not to let that happen.

“We left voluntarily to stop anyone getting arrested.”

The group said it planned more events to highlight the Tory lackey’s betrayal of the electorate.
