Buckles will appear during a Session that will also feature Sebastian Coe and Paul Deighton, the chairman and chief executive of London 2012, and Bernard Hogan-Howe, the Metropolitan Police Commissioner, and Chris Allison, national Olympic security coordinator. 

The Government were forced to draft in 3,500 extra troops after G4S admitted that they could not fulfil their obligations 

With just days to go to the start of the Olympics, G4S revealed it could not provide the required numbers of guards at the Olympics, forcing the Government to commit 3,500 military personnel to fill the security void and causing huge financial and reputational damage to the company.

The company had a £284 million ($442 million/€361 million) contract with London 2012 to provide 10,400 security guards for the Olympics, but only 4,000 guards were trained and ready by the time of the opening of the Games.

"The Committee intends to establish all the facts about the involvement of G4S in Olympic Security," said Keith Vaz, the chairman of the Home Affairs Committee.

"From the evidence we have received so far the Home Secretary and the Permanent Secretary are very clear that G4S failed to honour their agreement to provide sufficient staff.

"G4S were unable to give us a convincing account of what went wrong when they came before us in July.

"We are looking forward to hearing from them again on Tuesday, when they will have had exactly two months to investigate what led to the shambles we witnessed just before the Olympics was due to begin.

"Everyone now accepts that G4S let the country down at a crucial time.

"After this session, we will have heard from everyone involved in the process of overseeing Olympic security.

"We hope to ascertain the reasons why the security crisis happened and who else was responsible."
