A Labour MP has called for the government to publish the full details of West Ham United's proposed move to the Olympic Stadium.
The Hammers are due to leave their Upton Park ground ahead of the 2016-17 campaign, moving to the home of the 2012 athletics stadium, which is undergoing a £272m transformation.
Speaking in the House of Commons, shadow culture secretary Chris Bryant said: "This has the feel of a fiasco cooked up somewhere between the Mayor's Office, [Departure for Culture, Media and Sport] and the Treasury.
"Which is why, in the interests of transparency, I urge the government to publish the full details of West Ham's secret deal as a matter of urgency."
The club are contributing £15m to the costs of preparing the stadium for football, while UK Athletics has added £1m.
