The only thing I can add re that PFI disgrace is that it was a cute and convenient "kop out" for a government that didn't have the financial resources "up front" to deal with massive projects properly. Hence this cynical way to set up such projects on the "never, never" and "saddle" future govts/tax payers with the burden of paying off the equivalent of a long-term lease while the instigators (Blair et al) have "left the scene of the crime"!! Outrageously immoral but perfectly legal!!
