"For example, Tony Blair was supposedly on the 'left' but look at his record - hugely wasteful PFI schemes"
If you look at the record of the Blair government there's a consistent approach of taxing the future. PFI, student loans, Brown's stealth taxes. They look as if they're doing popular stuff but there were bills to become due in the future. We're now in that future.
As to whose side he was on, that's easy. His own.
