Again, it is this Government who are acting. That is why this substantive change is being made. It is precisely because of the damage that the hon. Lady describes that we are doing this. The argument we are having this morning is about the point in time at which implementation happens. What I have set out are not excuses but the reasons for the judgment that the Government have taken. Let us not forget that it is this Government who are making the change, and that their predecessors did not do so.
