Who are these barons?

And let me remind you of a couple of things. First, the Labour Party grew out of the trade Union movement. I for one want to see that strong link retained. Second, on the question of block votes, show me that the "barons" vote against the wishes of their members. I don't think you can. It's little more than received wisdom perpetuated by the right (as is "unions holding the country to ransom"). Third, crucial votes in the Commons are usually decided by block voting. We call it whipping.
