Olympic legacy bosses have decided to challenge a ruling ordering them to make public the details of their deal with West Ham over the Olympic stadium.
A consortium of fans secured the backing of the Information Commissioner in September but the London Legacy Development Corporation has always resisted complete transparency because it did not want sensitive financial figures revealed.
It says it will publish some more information about the arrangement but is now appealing the judgment.
An LLDC spokesman said: “The appeal relates only to information which if released could significantly reduce the level of financial return to the taxpayer as it would undermine negotiations with future users of the stadium and other partners.
“We have listened to the Commissioner’s comments and as a public body are committed to maximising transparency. As a result we will shortly publish more details of the agreement with West Ham United in all areas that fall outside the scope of our appeal.”
A West Ham spokesman said they support the decision to lodge an appeal, but added: “We are happy to disclose the entire document, the details of which have been accurately reported widely enough already.”
On the day of the ruling – September 15 – Mayor of London Boris Johnson said he was “perfectly happy” for details to be revealed. He is no longer chairman of the LLDC but oversees its work and was challenged by fans to use his influence to persuade the LLDC not to appeal.
The Olympic Stadium has been refurbished fit for football at a cost of £272million with West Ham contributing £15million. The club will pay about £2.5million a year.
LLDC argues that only a Premier League club could make the stadium viable and therefore the deal was good for taxpayers.
