It has been revealed that a further 3,500 troops will be on standby following an announcement from the contracted security firm that there may be problems providing enough trained staff for the Games.
Private security firm G4S has been paid in the region of GBP300m (US$460m) to provide 10,000 guards to protect the Games; however a senior spokesperson revealed the company may not be able to provide enough trained guards in time.
The British Armed Forces, who are already providing 13,500 troops to help at the Games, has been asked to provide a further 3,500, meaning summer leave has been cancelled.
A G4S spokeswoman told the BBC, "This has been an unprecedented and very complex security recruitment, training and deployment exercise which has been carried out to a tight timescale.
"We have encountered some issues in relation to workforce supply and scheduling over the last couple of weeks, but are resolving these every day and remain committed to providing a security workforce for the start of the London 2012 Games."
The London 2012 Olympics are set to begin on July 27th and run until August 12th. Despite this setback the UK government maintains there is no concern over safety, and released a statement saying, "Our approach is intelligence-led and risk-based, and we retain the ability to be flexible in our response.
"The government are committing GBP553 million for venue security and we remain confident that we will deliver within budget."
