West Ham delivered their bid to run the Olympic Stadium after the 2012 Games to 10 Downing Street on Thursday, insisting only they could deliver the legacy promise made when London was named host city.
Hammers players Scott Parker, Carlton Cole and Mark Noble took the joint proposal with Newham Council to the Prime Minister's residence after it was formally presented to the Olympic Park Legacy Company earlier in the day.
The plan would see the stadium's capacity reduced to 60,000 and it would host football and athletics, alongside other major sports, concerts and community facilities.
It would also house what the bid describes as "innovative and exciting education resources" and "health and well-being programmes", as well as an Olympic visitor centre and football museum.
Should the bid - which has been publicly backed by London 2012 chairman Lord Coe and UK Athletics chaiman Ed Warner - prove successful, Upton Park would be demolished, making way for new homes, shops and community facilities.
West Ham vice-chairman Karren Brady said: "We believe this is the only bid that can deliver London's legacy commitment to the International Olympic Committee.
"The last thing anyone wants is for the Olympic Stadium to become a ghost of Olympics past. The only realistic solution is to make the stadium work for a Premier League football team and that should be West Ham United.
"As a top-flight football club, we have the necessary expertise in running a major multi-purpose venue.
"Working with Newham Council, we could ensure extensive use of the stadium that would create prosperity in the local area and see this club grow and move on to another level.
"Our plan to keep most of the stadium in place protects the public investment."
