The troubled Millennium Dome is still on the market
The news follows reports that Housing Minister Lord Falconer of Thoroton had dropped plans to sell off the beleaguered former attraction following a series of aborted sales.
The conflicting accounts prompted Tories to press the Government for a statement in Parliament detailing negotiations for the Dome.
Tim Yeo, shadow culture, media and sport secretary, said he was fearful that more public money will be spent on the doomed site.
The row came after the Guardian newspaper claimed Lord Falconer had been considering plans to keep the Dome in public hands and to lease it out to private companies.
But a spokesman for Lord Falconer's office said on Saturday: "The Dome is still for sale and we are talking to a number of serious contenders to buy the Dome."
He said there was no timetable for the sale.
He declined to comment on speculation that the Dome might be leased while the land around it is sold off, stressing that such matters were "commercially confidential".
Mr Yeo said: "Yet again the Dome is causing embarrassment for the Government.
"After months of radio silence where ministers have refused to give any information about the progress on selling the Dome, we now learn that they may be unable to do so after all.
"A full public statement must be made to Parliament on Monday to assure people that yet more public money will not be thrown down into the black hole."
The Guardian reported that among the companies interested in buying a 10 to 20-year lease of the Dome is a US entertainment firm and a UK-based property consortium.
Discussions have already taken place between the two companies and the minister in charge of the Dome, Lord Falconer, the Guardian added.
Leasing the site could rake in much needed millions. Keeping the Dome standing empty cost £600,000 a month for the first six months of the year.
Bid withdrawn
Earlier this month, Britain's richest landowner, the Duke of Westminster, withdrew his bid to buy the Dome.
Grosvenor Estate Holdings, a property company owned by the duke, had formed a consortium with developers Stanhope, Quintain Estates and Lend Lease to turn the empty site into a theme park.
But Grosvenor and Stanhope have now pulled out of the Meridian Delta consortium.
