AS Spurs prepare to make its final pitch for the Olympic stadium today, Haringey Council leader Claire Kober has written a letter urging decision-makers to "put London first".
She has been backed by 11 other council leaders who believe West Ham's vision is the right one for the capital.
Tottenham Hotspur and West Ham United are expected to meet with Olympic Park Legacy Company to add further information to their bids particularly how they would ensure the Stratford stadium would be viable.
A decision on a preferred bidder would follow over the coming week.
The Premiership club has been based in Tottenham for the past 126 years where it has planning approval to redevelop a 56,000-seat stadium as part of a £450 million regeneration project.
In her letter, backed by 11 other council leaders, Claire Kober said: "The Olympic Games offers a once-in-a-lifetime opportunity to transform the lives of residents and this is a vital decision which must deliver lasting benefits for all Londoners, not just serve the interests of one football club."
She added: "The proposal put forward by Newham Council and West Ham offers a major boost to the continuing regeneration of London – building on the work already done around the Olympic site, whilst opening the door to a major redevelopment of the area around West Ham's existing ground and leaving the way clear for the much-needed development of Tottenham."
The letter ended with the plea to "put London first" and support the development that would "capture the spirit of the Olympic Games for decades to come, protect jobs and livelihoods, protect London’s investment, and bolster London’s rightful reputation as a global supercity".
Council leaders representing authorities including Barking and Dagenham, Brent, Camden, Islington, Newham, Southwark and Lewisham all signed the letter.
They agreed Spurs' intentions to knock down the £500m Olympic stadium and rebuild it to their taste was "an affront to taxpayers" who are funding the games through the GLA precept – the proportion of council tax paid to City Hall.
Copies of the letter were also sent to local government secretary Eric Pickles, culture minister Jeremy Hunt, Olympics minister Hugh Robertson and London mayor Boris Johnson.
