The boss of the company in charge of the Olympic Park’s future after the Games is to stand down on August 15, it was announced today.

Andrew Altman has been chief executive of the London Legacy Development Corporation - formerly known as the Olympic Park Legacy Company - since 2009.

He said he wanted to leave after having secured a successful post-Games legacy for the Stratford site, which will be renamed the Queen Elizabeth Olympic Park once the Games have finished.

Under his watch, the body has secured more than �400 million of funding for regeneration and infrastructure projects.

Mr Altman said: “It has been a tremendous honour to lead this once-in-a-lifetime project that will transform the face of London and will be a spectacular example of city-building the world over.

“I am proud to have been able to set the table with a clear vision, resources and commercial investment.

“It is now the perfect time to transition the project to one focused on construction, so there will no disruption after the Games in implementing the legacy vision we have crafted.”

The new 500-acre Queen Elizabeth Olympic Park will contain 7,000 new homes from next year, with most in the Chobham Manor neighbourhood made available as “affordable” housing.

Post-Games operators have also been secured for venues, including the aquatics centre, multi-use arena, Orbit and parklands.

Dennis Hone, chief executive of the Olympic Delivery Authority, will support the LLDC management on a part-time basis until a successor is found.

Daniel Moylan, incoming chairman of the LLDC, added: “Andy Altman has made a huge personal contribution to the future of the Olympic Park and we thank him for putting us in such a strong position.”
