The army to provide extra troops for Olympic security

"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."

"Our planning with Locog and other security agencies allows for a variety of contingencies which have been reviewed in the build-up to the Games. We accept that the Government has decided to overlay additional resources. We remain committed to keep London 2012 safe and secure."

"We have agreed to offer help to G4S by revising the level of military support.

The Government are committing £553 million for venue security and we remain confident that we will deliver within budget."

"The focus of the Government and everyone involved is on delivering a safe and secure Games. G4S are Locog's lead contractor for venue security and are being supported by the military.

"Our approach is intelligence-led and risk-based, and we retain the ability to be flexible in our response."
