I thank the hon. Member for Aberdeen North for her observations. She says that the principal rationale for a review is to consider whether certain measures might have been brought in earlier and, indeed, whether the original transitional measures should not have been introduced, or should have been done differently. I am not sure that that, in itself, is a strong justification for a review. What matters is that we look closely at how these measures will operate, and I am grateful for her recognition of the fact that our proposed changes are positive in that respect. I assure her that we will closely monitor the operation of the measures and whether any further changes are needed.
