The organisers of the London Olympics conceded defeat Wednesday in selling all the tickets for the football tournament as they revealed plans to slash the capacity of some stadiums. Organisers LOCOG said more than one million tickets were left unsold, but that figure has been cut in half by reducing capacity at venues including the Millennium Stadium in Cardiff. The changes mean that for the football tournament, 250,000 tickets are currently available. In addition to this, a further 200,000 football tickets are due to go on sale after being returned by Olympics committees from around the world. The top tiers of stadiums will be curtained off to hide the empty seats. A spokesman for LOCOG said: “We are planning to reduce capacity across the venues by up to 500,000 tickets across the tournament. “This will involve possibly not using a tier, or an area of a ground, in some of the venues. “This can apply to men’s and women’s football, if necessary.” A total of 700,000 Olympics tickets are yet to be sold, with 50,000 available for other sports as well as a soon-to-be-returned set of 200,000. Chief organiser Sebastian Coe insisted on Tuesday that ticket sales were “not in bad shape” despite LOCOG being forced to cut the size of stadiums. Coe said: “They are in reduced-size venues, of course. We have scaled down the size of those venues. “We’ve sold more football tickets than we’ve sold for anything else. “We’re not in bad shape on tickets. It was always going to be that football tickets were the challenge but I think we’ll do pretty well.”
