Legacy is in talks to take over the Millennium Dome after Japanese securities group Nomura pulled out after concerns over costs and future liabilities.
The consortium, which has been formed by entrepreneur Robert Browne, proposes to develop the site into a technology centre creating 9,000 jobs.
Press reports have said Legacy would keep the Dome at the centre of the Greenwich site, but would wait for the contents to be moved out before it moves in. However, the group could allow other businesses to set up in surrounding buildings. Site owner English Partnerships and Legacy refused to comment on what stage the talks had reached.
Meanwhile, the Dome has confirmed that pounds 1m is still overdue in sponsorship money but pounds 1.5m is not due until the end of the year. It also denied reports that McDonald's owes pounds 2.4m in sponsorship money.
'As far as sponsorship money is concerned, McDonald's doesn't owe us a penny,' said a spokesman for the Dome.
The claims follow a leaked report by PriceWaterhouseCoopers that appeared on the Sunday Times web site which claimed the project had no central check on incoming invoices.
