2 We collected information in order to obtain evidence that would allow us to answer the above questions. The majority of documentary evidence was provided to us by the Trust and its advisers. Certain additional information, particularly in respect of the refinancing of the contract, was provided by THC Dartford who carried out the refinancing and the Department who advised the Trust in connection with the refinancing. In the course of our study we also interviewed key staff within the Trust, including clinical staff, who are involved with, or affected by, the PFI project. The Treasury and its Refinancing Taskforce were also interviewed.
