Re: The long-term cost no one talks about..
Although it will hit the deficit I think paying off these PFI's will actually save money in the long run.
That is assuming that there is provision in the contracts for buying them out early, and I would bet a £ to a pinch of sh1t that there are (harsh) financial penalties for early pay - off involved anyway.
Unfortunately those who hold the contracts (many of which have been sold on as "investments", IIRC) also have the government taxpayers by the dangly bits.
