The hon. Lady is making a case for the need for assessment, but I ask her to look at the detail of the amendment, and in particular the reference to three months. The amendment would provide not for an assessment of the first three months, but that it would be published at three months. As good as Treasury civil servants are, that would mean they would have to start the assessment after six weeks and so probably would not even have the necessary data. Is not a slightly longer period more appropriate? Is there a drafting error in the amendment? Will the Opposition be looking for a slightly more sensible time scale?
