Joanne Jennings, chief executive of Liverpool One, Grosvenor's £1bn retail-led regeneration project, is to leave the company.
Jennings spent 18 months in the position, during which time the bulk of the 1.6m sq ft project has opened and she has established a 120-strong management team.
Jennings said in a statement today: "I have enjoyed a challenging and exciting role as the Liverpool One chief executive and am extremely proud of what has been achieved here, in particular the recruitment of a first class team and the delivery of an effective marketing campaign. I have also been very privileged to work in the city during the most momentous of times, with Capital of Culture and Liverpool's resurgence as a regional capital.
"I know that Liverpool One will continue to be embedded in city life. As we have now delivered Liverpool One's three year business plan, which will provide a road map up to 2011, I feel the time is right for me to move on to new challenges."
Miles Dunnett, Grosvenor's head of asset management for Liverpool One, added: "Speaking on behalf of Grosvenor and the other Liverpool One investors I would like to thank Joanne for all her hard work in helping to create the Liverpool One Management Company and managing it through the crucial transition period from development and grand opening into sustained service delivery. We wish her well for the future."
Grosvenor said it had reassessed the structure of the property management team and the role of chief executive role will not be replaced directly. A new position of estates director, focusing primarily on day-to-day operations and service delivery, will be recruited for early next year.
Jennings joined in April 2007 from Belfast City Centre Management Company.
