The interim chairman of the East Anglian Ambulance Trust has resigned early.
Dr Geoffrey Harris was brought in to turn round the leadership of the trust after it failed to meet targets for getting to emergencies on time.
In a statement, he said much work remained to be done but that the trust now had the right chief executive and was making improvements.
Work will now begin to recruit a new chairman.
