A decision on the future of London's Olympic Stadium has been delayed following weeks of debate on the tenants of the venue after the 2012 Games .

Premier League clubs West Ham and Tottenham have both submitted bids to use the stadium after the London Olympics, and a final decision was due on Friday.

But the Olympic Park Legacy Company said it needs more time to analyse each bid before making its decision.

An OPLC spokesman said: "Given the detailed nature of both bids received, we need more time to seek further clarification with both bidders in order to identify a preferred bidder."

"The stadium is a significant public asset and we have a duty to run a robust process."

"Securing the most appropriate solution for the stadium is vital to our long-term aspirations for the future Queen Elizabeth Olympic Park and the wider regeneration of the area."

Tottenham have tabled a bid which involves transforming the arena into a football-only venue, while West Ham intend to retain the athletics track at the stadium, as was promised in London's original Olympic bid.

Tottenham have offered to redevelop the ageing Crystal Palace National Sports Centre as compensation for the loss of the athletics track.
