Like AC1 points out, we the people, through our appointed agents/delegates the government, are party to these contracts. Yet they - our appointees - insist we can't be allowed to see the contracts they have signed on our behalf.
If you were an investor in a private company, and the CFO decided that all the contracts he'd signed with other firms were "commercially confidential" and you weren't allowed to see them, you wouldn't mess around: you'd seize the books and go through them with a fine-tooth comb to try and figure out what the bastard's embezzling, because you'd know the only possible reason would be because he's stealing.
I think the same applies here, and we've already got all the prima facie we need: pretty much every government minister in the past twenty years who has had pretty much anything to do with a PFI deal or privatisation has ended up working for the same people they've just signed the deal with or sold the public assets to, and almost always at a sinecure job paying them a vast fortune for a nominal day or two's work a week. And almost all of those deals and privatisations involve handing over massively inflated sums of public money or disposing of public assets at prices hugely below market rates. And the PFI firms always do a shit job and always ramp up their prices after the fact, and the government never complains, never sues them, never demands a refund, and is always keen to give them as many more contracts as they want, and it happens over and again.
How much more obvious does anyone need it to be?
