It's an interesting question, in the sense that it's something that the government has to pay and that we have to pay, regardless of future decisions, because the debt is a debt, and we have to pay interest on it.
We can look at what would have happened had we not seen an increase in debt or what would have happened in the absence of increases in interest rates. A simple way to look at that is to assume what would have happened without the increase in debt servicing costs. The simple answer is that it's money that could have been spent on other things—on, for example, reducing taxes—or spent on other proposals.
That's a highly hypothetical scenario, because we don't know exactly what would have happened in the absence of this additional debt servicing cost. Other decisions would have led us on a different track, obviously.
