London-2012: Games Security
Troops are being allocated 7,000 tickets for the dress rehearsals for the opening and closing ceremonies on top of the 10,000 Olympic and Paralympic tickets already assigned to them. G4S is expected to have its payment docked because of the problems but Mrs May said this was up to Locog, who agreed their contract. However, shadow home secretary Yvette Cooper said the situation looked like another "Home Office shambles" and Keith Vaz, Labour chairman of the Commons Home Affairs Select Committee, described it as a "fiasco".
London Mayor Boris Johnson, speaking at the Olympic Park, insisted: "Everybody is concerned to put the final nails in place - we always expected loads of military and I think they'll do a great job. The key thing is that it's going to be a safe and secure Games."
Defence Secretary Philip Hammond admitted increasing troop levels will put an extra burden on soldiers but promised they would be left out of pocket and would still receive their full leave.
The deployment comes as the Army reels from the announcement that it is losing 17 major units, including five infantry battalions, in its biggest restructuring for decades.
Assistant commissioner Chris Allison, head of Scotland Yard's security operation, has previously insisted the sporting event will be a "blue Games", despite the presence of the military and surface-to-air missiles being positioned near the Olympic Park. Security consultant Christian Cullen told Sky News it was "completely insane" to be enhancing military numbers now, after seven years' planning. Overall, a 23,700-strong security force will include a mix of military, private security guards and at least 3,000 unpaid London 2012 volunteers.
G4S said the security recruitment and training process had been "unprecedented and very complex" and admitted that it had encountered problems with its workforce. It said it was committed to keeping the event "safe and secure".
In May, the firm said as many as 100,000 people had expressed an interest in the 10,000 security jobs available and that it had already interviewed more than 80,000 for the roles. The private security firm contract is worth £284m from a £553m security budget, A further £600 has been allocated to the police operation but the Home Office hopes to deliver it for £475m.
