Olympic organisers say they are doing all they can to tackle the issue of empty seats at the London 2012 Games.

They have released 3,000 extra tickets after speaking to accredited people not using the seats.

There was criticism after many weekend events had rows of empty seats.

They were freed-up and sold overnight.

Many are believed to be those allocated to international sporting federations whose dignitaries have not turned up or public seats allocated for sale in foreign countries.

Officials say that pattern will continue everyday to ensure packed venues.

The tickets are being sold on the official London 2012 website.

Jackie Brock-Doyle is from the organising committee.

She says they are making progress.
