London 2012 Olympics: sale of remaining tickets delayed as organisers struggle to choose date At the moment we are just determining how it fits in the schedule of all the other things that are going on around there. Deighton said there was a crowded schedule of events that was delaying the timing of the ticket sales, which had been earlier flagged for April. Deighton said: "We have got test events, a command post exercise to test our command, control and communications systems. There is also a mayoral election. We just have to make sure that we fit the sale in around that so that it works as efficiently as possible. Officials say the delay is not related to ongoing issues with the Ticketmaster system failing to cope with high ticket demand. Uncertainty also continues about the Box Hill area of the road cycling course and whether Locog will charge spectators to access prime areas of the climb. Deighton said no decision had yet been made. Further confusion surrounds the creation of a Hoy Hill in the Olympic Park similar to Wimbledon's Henman Hill, with organisers still to determine how to sell access-only tickets and how much to charge. However after several days of scrutiny the IOC bosses declared "London will not disappoint" when it hosts the Olympic Games following an overwhelmingly approval of most aspects of the Games preparations and plans. But the IOC coordination commission chairman Denis Oswald warned London organisers not to be complacent and is keeping a watching brief on ongoing issues with transport, tickets and the budget. He told Telegraph Sport: "There are still some decisions to be made and they have to be made soon, the purchase of tickets for Box Hill, the ground passes for the Olympic Park and we are expecting more detail on the travel times between venues and hotels. The athletes need to know exactly the timings. For instance for the opening and closing ceremonies we know the time we have to be at the Park, but not what time we have to leave the hotel to be in the Park. Oswald also revealed that the chairman of Locog Seb Coe will not be lighting the Olympic cauldron on July 27. It's a decision for Locog. It doesn't necessarily have to be a big star athlete. It's not going to be me and its not going to be Seb [Coe]," said Oswald. Coe said of the next three months: "There is a mountain of work, but we have no time to lose. When the torch starts, people will recognise this is an extraordinary moment in the history of this country.
