London Mayor Boris Johnson says he would be 'perfectly happy' to have the details of West Ham United's move to the Olympic Stadium made available to the public.

West Ham are set to commence a 99-year tenancy at the venue of the 2012 London Olympics next season, but questions have continually been raised about how the Hammers were originally granted the lease two-and-a-half years ago.

The Hammers want to keep the details of the deal private in order to maintain their commercial confidentiality.

However, Johnson insists there is nothing to hide.

"I would be perfectly happy to publish the details of the arrangement," Johnson said.

"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.

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

"We did not want to put anything out that would impact on our ability to negotiate future contracts. But it should be a matter of public record and we should be very proud that we have got a Premiership football team in that stadium.

"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."
