Legacy plans for the use of London's Olympic venues after the 2012 Games could be undermined by "continuing uncertainty", according to new research from the London Assembly.

The report - produced by assembly's economic development, culture, sport and tourism committee - said concerns raised in July 2009 over the future of the Olympic Stadium had yet to be addressed. Although the Olympic Park Legacy Company (OPLC) is currently examining options for the venue, the study suggested the "character of the park" would be affected if a Premier League club relocated to the Olympic Stadium.

The committee also expressed concern that the Olympic Park could become an "island of prosperity surrounded by disadvantaged communities" if plans to provide affordable housing were not realised after the Games. According to the report: "The funding of the Olympic Park Legacy Company remains uncertain. Ongoing delays over the transfer of the Olympic Park land from the London Development Agency to the Company exacerbate this uncertainty.

"The allocated budget for initial transformation work after 2012 will not fund the long-term development of the park. At a time of restricted private and public sector investment, it is important a clear way forward for the Olympic Park Legacy Company is identified." Image: Olympic Delivery Authority
