The boss of British security company G4S says he's sorry that his company bungled its contract to provide staff to help protect the 2012 Olympic Games.
Nick Buckles told the BBC that "we are deeply disappointed" that the company wasn't able to make good on its promises to provide 10,000 people to help keep the games staff.
He says that the operation is a "mammoth undertaking" involving a "highly complex recruitment operation" in several different stages.
Buckles says the company has 4,000 staff "ready to go," having been trained and vetted, and received uniforms and instructions about their job. He says a further 9,000 applicants were in the process of being deployed.
Some 3,500 British troops are being called in to help fill the gap in security at Olympic venues.
