Malcolm Stamp has resigned as chief executive of University Hospitals of Coventry and Warwickshire Trust after 18 months.

Mr Stamp said in a statement he had “decided to take a break from the cut and thrust of the day to day management of large acute hospitals” and would initially work at NHS West Midlands on equality and diversity.

He has in the past been chief at Cambridge University Hospitals, Norfolk and Norwich University Hospitals and Royal Liverpool and Broadgreen University Hospitals trusts. He helped Cambridge achieve foundation status and has also been chief executive of NHS London’s provider agency and a health board in New Zealand.

Coventry and Warwickshire chair Philip Townshend said Mr Stamp had “set us well on the course” to foundation status. Deputy chief executive and chief finance officer Andy Hardy will be acting chief executive.

Meanwhile, Hull and East Yorkshire Hospitals Trust chief executive Stephen Greep is leaving the trust after eight years in post to return to academia and archaeology.

Chair Scilla Smith said: “He leaves our trust in a strong position and I would like to thank him for all of his hard work.”

Nursing director Mike Wright is acting chief executive and appointment of a replacement has begun.
