The London Legacy Development Corporation has said it is “disappointed” at being ordered to reveal full details of the deal surrounding West Ham United’s move to Stratford.

An information tribunal yesterday rejected the LLDC’s appeal against a London Assembly ruling that the contract between it and the Premier League club should be made public.

It means details of the funding for the Olympic Stadium, built for the London 2012 Olympic and Paralympic Games, must be published, amid suggestions of a lack of transparency over the use of public money.

An LLDC spokeswoman said they would consider the judgement “very carefully” before deciding on the next steps to take, which could include an appeal.

She added: “We are disappointed by the tribunal’s decision.

“We have already published the vast majority of the contract and only undertook this appeal following very clear legal advice that to release the remaining details could significantly impact the stadium’s ability to act competitively.

“The ruling will result in significant challenges given the commercial realities of a highly competitive market, which could amount to many millions of pounds being lost over the term of a 99-year deal.”

But the ruling has been welcomed by the Olympic Stadium Coalition, which is formed of 14 supporters’ trusts and groups.

It has long been campaigning for the details surrounding the Hammers’ tenancy of the 60,000-seater stadium to be made public.

A spokesman said: “We’re naturally delighted with the outcome, as we see this as an issue of fairness to the taxpayer, to clubs near and far, and to football as a whole.

“We now respectfully request that the LLDC do what is right, waive the right to an appeal, and publish the deal in full so that it can be properly assessed and its implications understood.”
