Guarantees have still to be approved for the use of signage by Olympic sponsors at Manchester United and Aston Villa football clubs as well as 1% of the 2700 sites controlled by the British Airports Authority (BAA).
Negotiations are ongoing between the 2012 bid team, the two football clubs and their sponsors over conditions for the proposed use of these venues at the Games.
A deal for the airport sites, currently covered by long-term contracts with advertisers, seems more straightforward given the BAA's status as a major partner for the bid.
London 2012 has a binding agreement with the BAA to take control of these sites in the event that existing advertising contracts are not renewed.
It is likely that the BAA would build a clause into new deals clearing the use of the sites by Olympic sponsors.
The IOC report put London second behind Paris.
