The deployment of British troops to provide security at London 2012 venues is a good strategy, says the president of the International Olympic Committee Jacques Rogge.
Rogge said he was "very, very confident" at the security operation in place, despite only being told private security firm G4S were struggling to fulfil their contract to employ 10,000 guards moments before details were made public.
He said it was now time to move on from the saga, which has seen the Government draft in an extra 3,500 troops to provide security cover at Olympic venues.
Speaking in an interview for BBC Radio 4's Today program, Rogge said: "Clearly LOCOG (London Organising Committee of the Olympic and Paralympic Games) and the Government wanted to communicate when all the corrective measures were in place and were operational.
"I think that is a good strategy. It's useless to give information where you have a solution for it. They have found a solution. We are happy with it and we are very confident that security will be very, very good.
"I believe, frankly speaking, in this debate we have to move on. The problem has been identified. The problem has been addressed in a good way. The company will compensate for the extra costs to the Government and really it is time to move to a different issue.
"What I am interested in, is the security arrangement OK, and it is OK. The end result is satisfactory. We are not going to enter in to a blame game. We are not going to point fingers because it is useless."
Rogge, who will meet the Queen on Monday during a reception for members of the IOC at Buckingham Palace, also defended strict rules to prevent ambush marketing by firms not signed up as sponsors to the games.
"We have to protect of course the sponsors, it goes without saying. You cannot ask a company to pay hundreds of millions of dollars and not be protected against ambush marketing," he said.
"But the fight against ambush marketing will be led with a lot of common sense. Everything that is in good faith will not be affected and will not be forbidden.
"If you come with a T-shirt and it is not exactly the T-shirt of the sponsor in the venue, they will not forbid you from entering the stadium. If it is a major attempt to do ambush marketing on a major scale then, yes, we will intervene."
The Olympic Games will be officially launched by the Queen on Friday and a spectacular STG27 million ($A40.97 million) opening ceremony created by Hollywood director Danny Boyle will be staged.
About 17,000 athletes and officials will be involved in the 17-day long Games which amount to 26 world championships.
