That was one of the main things that Seb Coe promised to address after the same empty Olympic seats were seen at Bejing and Greece (Australia don't do empty sports seats).

But I can see plenty of them in London as well. The reason being given is that they are the sponsors corporate gift seats that aren't taken up by those that aren't interested in the games or have more interest in mingling at the event champagne reception.

I would hope that they would start to start and give them away to those that pay a fiver for basic entry to the Olympic park if the freebee set don't fill them within half an hour of the event starting.

This is not just an Olympic problem, up to 10% of other major event seats remain empty for the same reason.
