The British political classes are going through one of their occasional bouts of masochism, with party leaders vying with each other on the theme of who can cut public spending faster and more effectively. Spice is added by talk of leaks and secret plans; and ideology by arguing about the balance between tax increases and spending curbs. My own bottom line is that all this is in response to a largely imaginary budget crisis. If we have a normal economic recovery the red ink will diminish remarkably quickly. If we don’t, it won’t and won’t need to.

All the secrecy and conspiracy-mongering is quite unnecessary and would soon disappear if ministers read the documents to which they attach their names and if opposition leaders, instead of searching in rubbish bins, did the same thing.
