Whether Nick Clegg retains his seat next year may be determined by the efforts of his local university to help their students register to vote.

Polling last week showed Mr Clegg has a perilous three-point lead over Labour in Sheffield Hallam - where 17.3 per cent of the electorate in the seat are students.

This a segment of the electorate that have turned drastically against the Liberal Democrats since the trebling of tuition fees in December 2010.

There have been concerns that changes to the electoral system being brought in at this election could make it harder for students to vote.

The next election will be the first time that the system of Individual Electoral Registration (IES), whereby voters have to register individually rather than by household

When Northern Ireland switched to IES in 2002, students were disproportionately affected by the transition. Because many students move accommodation from year to year, it is harder for Electoral Registration Officers to trace them to encourage them to re-register. The changes also affect students’ home addresses: under the new system, it will no longer be parents’ legal obligation to have them registered at home.

But Sheffield University, where a number of students live in Mr Clegg’s constituency, has been attempting to prevent the student vote diminishing – or even increase it.

It has liaised with Sheffield City Council to give new students the opportunity to be included on the electoral register when they register with the university.

It “offers a small but important step towards turning 'disaffected democrats' into 'contented citizens' ”, said Matthew Flinders, the Director of the Sir Bernard Crick Centre at Sheffield University.

Stephen Fisher, the co-author of a new Higher Education Policy Institute report on the electoral power of the student population added it could spell bad news for the Lib Dem leader.

“Given that Labour are now much more popular than the Liberal Democrats among students, increased registration of students in Sheffield looks more likely to harm than to help Clegg’s chances of re-election,” he said.

However unlike Sheffield University, the city’s other university Sheffield Hallam, has - like the vast majority of higher educations throughout the UK - so far failed to follow Sheffield’s lead on voter registration.

Nevertheless, the HEPI report estimates that students voting differently to national trends will determine around 10 seats. This is expected to largely benefit Labour at the expense of the Conservatives and Lib Dems. The student vote could also benefit the Green Party: 25 per cent of students backed the party in the European elections. The Greens are targeting Bristol West, where 24.3 per cent of the electorate are students, as the most likely source of a second MP.
