So far as the spin cycle's concerned, Byrne's remarks are striking for two reasons. First, they show just how determined Labour are to stick with a "Tory cuts" attack. And, second, they represent a return to the charge that behind the "Cameron veneer" lies a bunch of unreconstructed, "nasty" right-wing nutjobs.
Problem is, the political tides are set against Byrne. Labour themselves pencilled in £35 billion worth of "cuts" in the PBR. And, given how dramatically the public finances have sunk since then - with borrowing set to top £2 trillion - they'll need to cut back even more in subsequent Budgets. In the meantime, articles like Byrne's come across as dangerously complacent about the scale of the problem.
