ok. bear in mind this is not exhaustive, this is off the top of my head.
-PFI
-iraq war
-turned a blind eye to the banks getting in over their heads
-overly friendly with oligarchs (mandelson) and allowing ridiculous tax loopholes for the super-rich
-selling off gold reserves when gold was at an all-time low
-dithered about bailing out/then nationalising the banks when they realised they were in over their heads
-getting rid of 10p tax rate
-social mobility is getting worse, not better
-starting wars then underfunding the defence forces (i'd prefer they didn't start wars, but if you're going to start them you need to do it right)
-iirc, pretended we'd have a referendum about the lisbon treaty then changed mind
-blatantly admitted to refusal to listen to scientific evidence regarding drugs policy
-knife/gun policy- you get almost more jail time for carrying a weapon than using it (if you're convicted of manslaughter rather than murder)
-ridiculous anti-terror laws
-use of said ridiculous anti-terror laws against iceland, that well-known al quaida heartland
- ID cards
- CCTV everywhere
and as i said, that's off the top of my head. there are bound to be far more.
don't get me wrong, they've done some good things too. and the tories would have done all that and worse. But I'm darned if I'm going to say they're any good, either. Lesser of two evils, that's the best they're getting from me.
