West Ham United owners David Gold and David Sullivan have been handed a setback in their hopes of moving to the Olympic Stadium in Stratford.
With the 2012 Games to be held in London, the club's hierarchy admitted they would welcome a switch to the 80,000 capacity venue following the event.
However, Olympics minister Tessa Jowell has poured cold water on their ideas, saying:"Let's be clear about this. It will be a grand prix athletics stadium because we need one.
"We have made that commitment, that was one of the reasons that we bid to win the Games and so that is a given."
Jowell has also expressed her dismay with the Hammers bosses publicly expressing their desire to relocate, and has insisted that any potential move would be sanctioned by the Olympic Park Legacy Company.
She added:"I don't think you can jump from a press conference where the new owners sit down and say we'd like to move to the Olympic Stadium to how it might work.
"In order to make sure we maximise the legacy of the park, we've set up the Olympic Park Legacy Company and they will shortly be inviting bids and business plans from any business that wants to apply for a commercial stake in the stadium and, if West Ham want to made a bid at that time, it will be considered alongside all the others."
