"It’s often said that the UK is in hock. The national debt is, according to some, going to cripple us. I have already made a video explaining why this is nonsense. We need our national debt. But implicit in this suggestion that the national debt could cripple us is another idea, which is that there must be some 'dark powers' who own at least a part of the national debt to hold us all to ransom and deny any government the power to do what it wants, whatever an electorate wants. That’s why it’ worth knowing who owns the national debt, which is what this video is about."
