Tottenham Hotspur, West Ham’s main rivals in the bidding battle for the Olympic Stadium, would demolish most of the 80,000 athletics arena and replace it with a 60,000 football-dedicated venue.

Differences in the rival bids became clearer yesterday as the north London club outlined their vision for the Stratford stadium after the 2012 London Olympic and Paralympic Games.

Spurs said two-thirds of the Olympic stadium, including the steel that provides the temporary seating structure and the seats themselves, would be demolished.

The stadium’s athletics track would also be removed to be replaced with a 60,000-seater stadium.

That would reportedly cost �200m less than Spurs’ alternative plan to redevelop their current White Hart Lane home.

The club would also revamp the Crystal Palace athletics stadium as part of their contribution towards the legacy commitment made when Great Britain was awarded the Olympics in 2005 and an athletics legacy fund would be set up.

East London rivals West Ham plan to retain the athletics track and use the stadium for other sports such as athletics and cricket in summer months.

David Keirle, chairman of the KSS Group architects who are working on the Spurs bid, suggested the Olympic Stadium as it stood would have insufficient facilities for a football club.

He said: “All the concessions are outside, it has no toilets, suites, boxes and very limited hospitality.

“It doesn’t have a roof.”

Sebastian Coe, the chairman of London 2012 and UK Athletics both put their backing behind the Hammers’ bid last year.

The Olympic Park Legacy Company is expected to announce a preferred bidder by January 28.
