Pam Alexander, chief executive of English Heritage has announced that she will resign in September.

Alexander, who has been with English Heritage since 1997, has been responsible for overseeing a significant period of growth and development in the organisation, including the establishment of a more regional structure, and the co-ordination of government reports on the sector.

Although links have been made between the controversy involving King Constantine of Greece being permitted to hold a private function at Kenwood House at cost, and Alexander's sudden resignation shortly before the five-year reorganisation plan, English Heritage denied the allegations.

Alexander said that she enjoyed her time with the organisation: My time at English Heritage has been hugely challenging and rewarding. I leave English Heritage having created a stronger and more robust organisation, closer to its customer and working as a key partner at regional level to deliver local services in response to local needs.
