A further 1,200 military personnel are being deployed to help secure the 2012 Olympics in London following the failure by security contractor G4S to provide enough private guards. The extra personnel have been drafted in amid continuing fears that the private security contractor's handling of the £284m contract remains a risk to the Games.
