If the voters will believe you, then a good way to get elected is to promise them that your government will spend less of their money and, at the same time, provide the people with more generous services. It is hardly a novel approach. But, provided the voters are not convinced by any alternatives they are offered, it can work. And in May 2015 at least in England although not in the rest of the United Kingdom, it did.
Having promised both things, how is the trick actually going to be done? And what will public management in Britain be like for those running our public services over the next five or even ten years?
