I thank my right hon. Friend for his kind support and also his advice. He is of course absolutely right, and I hope that he was heartened by what he heard me say in the statement about the importance of returning our public finances to a sustainable footing in the medium term. We can and will do exactly that. He is right to highlight the sensitivity of our debt to interest rates, which was why he was right to introduce into our fiscal framework the notion of an interest service rule, and that is something that I will look at keenly in the coming months.
