Oxford University vice chancellor Dr John Hood has confirmed he will not be extending his five-year term in the post.

Recent university regulations allow for an extension of up to two years in certain circumstances.

But Dr Hood has written to the Chancellor of the University, Lord Patten of Barnes, to confirm he does not wish to extend his tenure beyond September 2009.

Dr Hood said: "I continue to believe that five years is the right period. That was the commitment I made on my appointment as vice chancellor and it remains my view today.

"That will be the appropriate time for me to hand on the immense privilege of leading this great university."

Lord Patten chairs the committee responsible for nominating a vice chancellor. University regulations require the committee to recommend a name for approval by the university at least 12 months before the expiry of an existing five-year term.

Lord Patten said: "John Hood is doing a remarkable job as vice chancellor.

"Under his leadership the university's global reputation, academic standing, financial strength, and internal organisation are all continuing to advance.

"Two of the hallmarks of his tenure are the clarity of his vision and the strength of his commitment.

"Both are powerfully present in this decision, which allows the university both to plan for the future and to continue to benefit from John's outstanding leadership for the next two years without unnecessary distraction."
