My esteemed flatmate tipped me off to this amusing diversion in which you get to play George Osborne. Regrettably, you can only choose how to wield the knife over the budget, rather than getting to play the presumably far more interesting game of hunting down children by night and sucking out their life-force so as to live forever, but it's still interesting.
Turns out you can easily make the same number of savings simply by scrapping our second new aircraft carrier, a wing of Typhoon fighters, and Trident in its entirety. Oh, and Wales and Scotland. I don't think that's too high a price to pay. We can just relabel extinction as "extreme devolution" (i.e. they're being devolved from, you know, living organisms) and we're good to go.
Though now I think about it, I've scrapped all the nukes, haven't I? Damn, this chancellor lark is a bit tougher than it looks on telly.
