I do not know whether the hon. Gentleman is asking what the costs of running the system will be, but if he is, the draft regulatory impact assessment-I do not know whether he has had a chance to look at it yet-sets out our provisional estimates of the marginal costs of creating this functionality in the system. They are £45 million, with annually recurring costs of around £4 million. However, I should say to him-I am grateful for the chance to emphasise this-that a lot of that will depend on the detail that the Scottish Government and other stakeholders wish to see on documentation such as P60s. That will influence where those costs fall.
