Data on grant and loan overpayments are held by the Student Loans Company (SLC), but are not sub-divided by the reason for each overpayment.

Grants are paid up front to students based upon the latest information provided to SLC about individual students' circumstances. Overpayment generally occurs when the SLC receives information from a student or their higher education institution that the student's financial circumstances have changed, or that they are no longer attending their course of study, which leads to the grant amount being re-assessed. Figures on overpayment are reported by academic year, and the most recently completed academic year for which figures are available is 2011/12. They show that 49,300 customers were overpaid grants amounting to £69.1 million. These figures are subject to change as SLC receives new information and re-assesses overpayment amounts in the light of this.

It is not possible to provide a complete assessment of loan overpayments. This is because overpayments of loan are only recorded as such until such time as the person becomes liable to begin making repayments. After that point, the overpaid amount is recorded as part of the loan balance, which is generally recovered via the tax system. Figures for borrowers who have received an overpayment of loan and who are not yet in repayment were published in the answer I gave to the hon. Member for Sheffield Central (Paul Blomfield) on 18 April 2012, Official Report, columns 385-6W.

The UK has made a major contribution to graphene research, since its discovery in 2004 and the Nobel prize for Professors Geim and Novoselov of Manchester University in 2010.

We are investing £60 million in graphene of which £38 million will be used to create a National Institute of Graphene Research at the University of Manchester.

The Engineering and Physical Sciences Research Council (EPSRC) have invested £10 million on linked manufacturing processes and technologies.

Universities will be working with industrial partners including Dyson and BAE who are expected to provide an additional £12 million. We expect UK universities and businesses to benefit from the new €1 billion investment in graphene by the EU.

The Government have established a new framework, which places more responsibility on universities and colleges to widen participation. We will ensure that widening participation for students from all backgrounds remains a key strategic objective for all higher education institutions. We believe it is valid and appropriate for institutions to seek to broaden access while maintaining excellence, so long as individuals are considered on their merits, and institutions' procedures are fair, transparent and evidence-based.

All institutions that intend to charge more than the basic £6,000 annual tuition charge have to demonstrate to the satisfaction of the independent Director of Fair Access what more they will do to attract students from under-represented and disadvantaged groups. A new National Scholarship programme began this year. By 2014, it will provide £150 million to help improve access to higher education amongst the least well off young people and adults. All higher education institutions charging over £6,000 will be required to participate in the programme

We wrote on the 22 May to both the Higher Education Funding Council for England (HEFCE) and the Office for Fair Access (OFFA) asking them to develop a shared strategy for promoting access to higher education and maximising the impact of the spending by Government, HEFCE and institutions. We asked them to consider how total investment might be best targeted to deliver impact. It is vital that all the relevant spending is based on the best possible evidence base and harnessed to drive systematic improvements.

The Government have published a measure of the gap in progression to the most selective higher education institutions by school type. This measure was developed as part of the Government's social mobility strategy.
