So what.ffreeloader wrote that "he UK is socialist. They have nationalized, put government in control, of most, if not all, of their industries."- so you 'prove' this by throwing the 1945 labor party platform at me! And they aren't even in power now!
"They have nationalized, put government in control, of most, if not all, of their industries."
And they have. Why are you claiming that they haven't?
Was socialism repealed? Did the U.K. repent of socialism? Did they they say they over-reached when they stole private property?
So, they sold some of their stolen property under Thatcher. Is there anything stopping them from stealing it again? Was there a truth and reconcilliation panel where the labor party apologized for being evil and admitted what they did was wrong? No?
Once a country says it's alright to taking property for the common good, there is no going back. The U.K. is capitalist in name and some practices, but like China and Russia, they retain socialism as their basis.
The U.K. reserves all rights to nationalize anything it wants. And that makes the U.K. socialist.
