You do appear to get quite animated by this, so I've helpfully provided some figures for you to place the issue into context.
The Treasury has useful spreadsheet on its website which list the various PFI deals, shows which government signed off the deals, the capital value of the projects, profile of repayments and so on. Unsurprisingly, they do show the very large majority of deals being signed off by the Labour government.
As of end March 2023, the latest data available, there are 669 deals outstanding in total, with a capital value of £50.2bn, resulting in repayments of £278.3bn.
The Labour government signed off 576 of these deals, accounting for £42bn of the capital value and £246.7bn of the repayments. That's 89% of the cost of the deals. They also signed off a deal just 5 days before the 2010 election, so they clearly didn't discontinue the use of PFI at any point.
Interesting figures given the speculation of Reeves reintroducing PFI. She can't be that dumb, can she?
