London 2012: Organisers 'selling unused tickets' for Olympics
Cannot play media. Sorry, this media is not available in your territory.
London 2012 organisers Locog say they have sold an extra 3,000 seats to events on Monday after they were returned to them by sports federations.
Labour have called for unused tickets for the Olympic Games to be given to police, soldiers, teachers, and school children.
The Director of Public Affairs at Locog, Jackie Brock-Doyle, told a news conference that they were doing all they could to fix the problem.
