Video: London 2012: Chief Executive of G4S apologises for Olympics security shambles Chief Executive of G4S, Nick Buckles, apologised for the problems surrounding security at the Olympic Games, which Labour described as a "shambles," saying he accepted he may have to quit as a result. At a Home Affairs Select Committee hearing, Mr Buckles insisted he was the right man to make sure the firm delivered as many Olympic guards as possible, despite the on-going security debacle. He said he was sorry and deeply disappointed after the firm, which is running the £284 million contract for Games security, failed to meet its targets. He is under pressure to quit his £830,000-a-year job over the fiasco, which has resulted in the emergency deployment of soldiers and police officers and seen £400 million wiped off the market value of G4S.
