The real worry, though, is that Gordon Brown trashes the public finances so comprehensively in the next PBR before going to the polls that it becomes more expensive for this country to borrow:
“The Pre-Budget Report assumed that the Government would continue to pay an average interest rate of only a little over 4 per cent on its debt. There are good reasons to hope that this will remain low, but if investors decide that they would prefer to lend to governments other than our own, then the fiscal arithmetic will become a lot more unpleasant. This underlines the need to persuade them and us that the public finances will be repaired.”
The Tories, if they win power, will face a mighty challenge in fixing the public finances. If borrowing became more expensive, it would be far more difficult.
