Social Security

I am grateful to the hon. Lady. I have heard it intimated that the Opposition support using a temporary measure of inflation before using a different one in the future. I can see the politics of that, but not its coherence. The duty on my right hon. Friend the Secretary of State is to measure the general increase in price levels in an appropriate way, and it would be very odd if he were to decide one year that the CPI, with its method of calculating on a basket of goods, was the right answer, and then four years later, because there was a bit more money, that there was a different answer. That is not the legal duty on my right hon. Friend.
