The 2012 Olympic Stadium will house a school rather than a Premier League club after the Games under legacy plans for the 500 million pounds venue, London Mayor Boris Johnson said.

"In the end there were insuperable obstacles with the shape of the stadium," he told reporters at the launch of a detailed masterplan for post-2012 which includes building 10,000 new homes and creating 10,000 jobs in east London.

"It would also have cost far, far more in the end to create a stadium suitable for Premier League football."

When Johnson was elected last year he was critical of the lack of a blueprint for the legacy use of the 9.3 billion pounds Olympic Park and surrounding areas and appointed a board of advisers to maximise its use.

As well as a sport's academy for 400 secondary school pupils inside the stadium, there are plans for the English Institute of Sport and a National Skills Academy to be based there.

Johnson said the stadium, which will be scaled down from its 86,000 Olympic-capacity, will host international athletics events as well as other sporting events and concerts.
