Locog stops G4S payments over Olympics security fiasco In a thinly veiled criticism of G4S, Mr Deighton noted that Locog had managed to successfully deploy 70,000 volunteers to work during the Games, about seven times the number of guards the FTSE 100 company had agreed to supply. G4S had been asked to deploy 10,400 guards at peak times during the Olympics, but managed just 7,800. Appearing in front of the Committee at a later session on Tuesday, G4S chief executive Nick Buckles said the company would be negotiating penalty payments with Locog but said he expected the company to be paid for the work it did. I'm not going to sit here and say we did a great job, but we delivered a significant proportion of the contract. I expect them to pay us in line with the terms of the contract. Mr Buckles" future at G4S remains uncertain as the board awaits a report from PricewaterhouseCoopers on what went wrong with the contract. He said that he had invested a big part of his life and career into the company but said he would wait to see the outcome of the report, which is expected by the end of this month. Mr Buckles added: "I'm group chief executive, and if a contract goes wrong I take the pain of that." Speaking after the sessions, chairman of the Committee Keith Vaz said: I think it's absolutely clear that Locog is right not to be paying them anything ... but it's also clear that [G4S] admitted full responsibility for what's going on and I would imagine Mr Buckles realises the buck stops with him. Shares in G4S fell 2pc - or 5.1 - on Tuesday to 255.6p.
