Thirteen Oxford University colleges failed to make a single offer to black A-level applicants over a six-year period, new figures have revealed.

Between 2010 and 2015 only three of Oxford's 32 colleges made an offer to a black A-level applicant every year.

And nearly one in three Oxford colleges failed to admit a single black British A-level student in 2015.

Labour MP David Lammy, the former higher education minister, accused the university of "social apartheid" after obtaining the figures through a Freedom of Information (FOI) request.

Mr Lammy is calling for reforms to the Oxbridge admissions process in light of the findings.

The data also shows that 48 per cent of Oxford offers went to applicants from London and the South East, compared to 15% from the North, 11 per cent from the Midlands and 3 per cent from Wales.

Mr Lammy said: "Overall, the picture painted by this data is of two institutions that overwhelmingly draw their students from a privileged minority in the South of England and are complacent at best about taking steps to widen participation and access."

Dr Hugh Rayment-Pickard of Blackbird Leys-based IntoUniversity, who encourage school students to apply to university, said: “This is a long-term problem which requires a long-term solution.”

He said that their team works with primary school pupils to influence future aspirations early on. 

They have worked with 1200 local young people in the Blackbird Leys area and 36 of the students they have worked with across the UK have gone to Oxford University in the past four years. 

A lecturer who was rejected by Oxford as a student but now works in the History Department and has been involved in the admissions, said he had found the whole process 'completely nuts'.

"We need new ways of making outreach work and attracting applicants. 

"Students need to know Oxford is for them" she said. 

A spokesman for Oxford said fixing the issue would be "a long journey that requires huge, joined-up effort across society - including from leading universities like Oxford - to address serious inequalities".

"We're working with organisations such as Target Oxbridge and the newly formed Oxford black alumni network to show talented young black people that they can fit in and thrive at a university like Oxford. All of this shows real progress and is something we want to improve on further," the spokesman said.
