Mr Kiley, in a letter to Peter Hornsby, principal inspector for the Health and Safety Executive (HSE), says: "One cannot read the PPP contract documents with any degree of care and conclude that LU has adequate control over safety. What few theoretical controls it does have will be extremely difficult to exercise, because of the complexity of the contract documents, because of loopholes in the documents and because LU cannot possibly have sufficient personnel resources to exercise these controls."
