It seems pretty clear that tranche A of military (7,000 or so pax) were mobilised for Op Olympics some month ago, and that tranche B (the additional 3,500) only in the middle of this week. So I think it is totally possible that both Hunt and May were telling the truth, and that each mobilisation shows that the Govt and LOCOG acted at the times they knew.
Who scrutinised and signed the contract with G4S?
Why was it not properly monitored? And why is their actual performance not being checked? That only 17 out of 56 guards turned up for work, and had the police not noticed (and that was serendipitous - they do not appear to have a formal role in monitoring G4S performance), would it have gone unnoticed?
Why the supine attitude to private contractors from Hunt? Are G4S under- performing in their many, many other Government contracts? When were those contracts signed? What performance monitoring is going on? Who is holding them to what performance measures?
