More than a quarter of graduates were not in full time work three and half years after leaving university, new figures show.
University leavers are also becoming more likely to be unemployed, the statistics suggest.
Data published by the Higher Education Statistics Agency (HESA) reveals that 27.7% of UK graduates who left university in 2006/07 were not in full time paid work three and a half years later.
Some 8.8% were in part time paid or voluntary and unpaid work, while 5.3% were working and studying, and 6.5% were just studying.
But 3.6% were assumed to be unemployed, the statistics show.
This is higher than in other years.
