Boris Johnson: We got a very good deal

The London Legacy Development Corporation and West Ham, had insisted the deal for the largely taxpayer-funded stadium should remain private for reasons of commercial confidentiality but, speaking before a tribunal ruled the 207-page document should be made public, Johnson said he had no issues with the document being made public.

"I would be perfectly happy to publish the details of the arrangement," Johnson said at the London Assembly Mayor's Question Time back in September.

"I understand the football club concerned is not so keen because they think it will give other clubs an inside into their finances and so forth."

The Hammers take over on a 99-year deal from next season, but the decision has been heavily scrutinised since it was first announced two and a half years ago.

"We have been very up front over not publishing the details so far as we have only just concluded the final letting contracts,' Johnson said.

"We did not want to put anything out that would impact on our ability to negotiate future contracts."

The decision to publish the details of West Ham's successful bid for the stadium was dealt by a Freedom of Information request, and, while the LLDC had challenged that decision, Johnson believes it "should be a matter of public record."

He said: "We should be very proud that we have got a Premier League football team in that stadium.

"The stadium has been a fantastic success. It is doing brilliantly and it is basically unlike any other Olympic Stadium around the world as it has a long-term viable future with Premiership football at the heart of the deal.

"I thought that was the right way forward for London and the right way forward for the Olympic Stadium. There are Olympic Stadiums around the world that are totally mothballed and don't have any real activation in them. Go to Athens, go to Beijing.

"It was perfectly obvious to me that the stadium could not have had a long-term future without a Premiership club in it.

"We've got nothing to hide, we've got a very good rental agreement with West Ham and it's fantastic that we will not be spending any more public money on this, so let's get it out there."
