Why does anyone actually use G4S - they usually have staff on gatelines who probably wouldn't know what a train was if they walked into one, and they can't get themselves organised to provide the security staff in time for the Olympics (which has hardly "sprung up" on anyone)? Always a tale of woe!BBC News said:There is "no question" of Olympics security being compromised, the home secretary has said, after it emerged 3,500 extra troops would be needed.
Theresa May said it was discovered only on Wednesday - 16 days before the Games begin - that contractor G4S did not have enough trained security staff.
The troops are in addition to 7,500 already agreed for venue security.
Labour MP Keith Vaz said: "G4S has let the country down and we have literally had to send in the troops."
G4S was contracted by the London 2012 Organising Committee to supply 10,400 staff out of the 23,700 security staff needed for the Games.
It said it had 4,000 people already working across 100 venues.
It also said there were a further 9,000 people going through the final stages of extensive training, vetting and accreditation.
