The Chief Executive of Kettering General Hospital has resigned.
Lorene Read, who held the position for nearly two years, made the decision after the hospital consistently failed to achieve the national target for accident and emergency transit times.
The target is for 95% of A&E patients being either admitted to discharged within four hours. In Kettering the figure was 85.2% between April and June 2013 and 93% in July and August.
Clare Culpin, Director of Nursing, will be acting Chief Executive. The Trust hopes to make a "substantive appointment at the earliest opportunity".
