Following it on a feed. Bankers..blah...renationalise railways...blah...living minimum wage...hang on, did he just say he wants to remove the council spending cap and let them borrow against their housing stock? Ermmm...borrow from whom exactly? Would it be...banks? who, if not paid back would presumably be entitled to repossess council properties?
Did he also suggest that he possesses a mandate and Theresa May doesn't? Dear God, he actually doesn't appear to understand how our political system works at all!
I had a rather robust exchange with his Royal Highness Ian of Harvey on Facebook about the banking crisis. No matter how hard I tried I could never get him to understand, or at least admit he understood, that the banks who lent irresponsibly were lending to people who were borrowing irresponsibly, and that those people were also to blame.
Nope, it was the banks. People, provided they are working class, are always the victims. I expect Jeremy and Ian would get along famously.
