The former head of an Oxford business school has hit out at falling standards at Oxford University.

John Kay, who resigned last year as the head of Oxford's Said Business School, warned that if the decline continued, the University would not be able to compete with leading American colleges like Harvard and Stanford.

Mr Kay was speaking following the publication of this year's performance table which showed that Oxford had slipped to third behind Cambridge and Imperial College, London.

He attributed the decline to its "morass of committees" run by academics untrained in management or business.

But an Oxford University spokesman hit back, claiming: "There is no doubt that Oxford remains a pre-eminent world-class university."
