As one of the opening captions put it, "you couldn't make it up", and this sprightly drama about the House of Commons expenses scandal duly tacked its way skilfully up the channel between satire and slapstick. Concluding correctly that wallowing in moral outrage was not the way to handle a subject whose full ramifications have yet to land on us (and them) with their full crushing force, writer Tony Saint instead deftly depicted the Commons as a kind of Swiftian monstrosity, ludicrous yet malevolent.
